The periodic table of the chemical elements (also known as the periodic table or periodic table of
the elements) is a tabular display of the 118 known chemical elements organized by selected
properties of their atomic structures. Elements are presented by increasing atomic number, the
number of protons in an atom\'s atomic nucleus. While rectangular in general outline, gaps are
included in the horizontal rows (known as periods) as needed to keep elements with similar
properties together in vertical columns (known as groups), e.g. alkali metals, alkali earths,
halogens, noble gases.
Periods
A period is a horizontal row in the periodic table. Although groups are the most common way of
classifying elements, there are some regions of the periodic table where the horizontal trends and
similarities in properties are more significant than vertical group trends. This can be true in the d-
block (or \"transition metals\"), and especially for the f-block, where the lanthanides and
actinides form two substantial horizontal series of elements.
Periodic trend for ionization energy. Each period begins at a minimum for the alkali metals, and
ends at a maximum for the noble gases.
Elements in the same period show trends in atomic radius, ionization energy, electron affinity,
and electronegativity. Moving left to right across a period, atomic radius usually decreases. This
occurs because each successive element has an added proton and electron which causes the
electron to be drawn closer to the nucleus. This decrease in atomic radius also causes the
ionization energy to increase when moving from left to right across a period. The more tightly
bound an element is, the more energy is required to remove an electron. Electronegativity
increases in the same manner as ionization energy because of the pull exerted on the electrons by
the nucleus. Electron affinity also shows a slight trend across a period. Metals (left side of a
period) generally have a lower electron affinity than nonmetals (right side of a period) with the
exception of the noble gases.
Hope this explains your daughter.... :)

The electrons which are involved in bond formatio.pdfrakeshankur
The electrons which are involved in bond formation between atoms are found in the
outermost shell (sometimes in the next to the outer-most shell) of the neutral atom; these are
called VALENCE ELECTRONS. The atoms of elements which have only one or two electrons
in their outermost shells (active shells) may lose electrons when they combine with atoms of
other elements. An atom which has lost one or more valence electrons possesses a positive
charge, and is called a POSITIVE ION. The sodium atom loses its one valence electron and
acquires a +1 charge when it enters into chemical combination with an atom of an element such
as chlorine. The magnesium atom may lose its two valence electrons and assume a +2 charge.
Na Na+ + e- The Na symbol to the left of the arrow represents a stable sodium atom while the
Na+ symbol to the right of the arrow represents an unstable sodium ion which has had a single
electron removed. Mg Mg++ + 2e- The Mg symbol to the left of the arrow represents a stable
magnesium atom while the Mg++ symbol to the right of the arrow represents an unstable
magnesium ion which has had two electrons removed. The smaller the number of valence
electrons in the atom, the greater the tendency of the element to lose electrons and thus form
positive ions during chemical combination with atoms of other elements. The energy required to
remove an electron from a neutral atom to form a positive ion is called the IONIZATION
POTENTIAL of the atom. Some metals have small ionization potentials and readily form
positive ions. The nonmetals, which have more electrons in their outer shells than the metals,
have large ionization potentials and show little tendency toward the formation of positive ions.
Atoms which lack one or two electrons of having an outermost shell of eight electrons readily
gain sufficient electrons from certain other atoms, such as sodium and magnesium, to make a full
compliment of eight electrons in the outside shell. Neutral atoms become NEGATIVE IONS by
gaining electrons. The nonmetals, such as Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I),
Oxygen (O), Nitrogen (N) and Sulfur (S), readily form negative ions. Cl + e- Cl- Chlorine,
when in its stable form, possesses seven valence electrons and therefore has the ability to gain
one electron (as represented to the left of the arrow) giving it a negative charge of one when in
its unstable ionic form (as represented to the right of the arrow above). S + 2e- S-2 Sulfur, when
in its stable form, possesses six valence electrons and therefore has the ability to gain two
electrons giving it a negative charge of two when in its unstable ionic form. The attraction of a
neutral atom for electrons is known as its ELECTRON AFFINITY. The nonmetals have high
electron affinities and the metals have very low electron affinities. Thus, mainly the nonmetals
tend to form negative ions during chemical combination. When a positive ion and a negative ion
are brought close together, strong electr.

Effects of NaCl Concentration on Red Blood Cell Volume A red blo.pdfrakeshankur
Effects of NaCl Concentration on Red Blood Cell Volume
A red blood cell (rbc) will attempt to regulate its volume when placed in a solution of
impermeable substances dissolved in water (Randall, 1997). A solution is considered to be
isosmotic when it has an osmolality equal to that of normal plasma (Freedman, 1998). The
osmolarity is the osmotic pressure that a cell effectively has exerted upon it (Randall, 1997). The
osmotic pressure is the pressure that is created by osmosis between different solutions that are
separated by a semipermeable membrane (Randall, 1997). If a rbc is placed in an isotonic
solution, the cell will maintain its normal volume because no osmotic pressure is developed. A
hypotonic solution has a lower concentration of solutes than the interior of the cell. Therefore, a
hypotonic solution will cause water to flow into the cell, as the concentration of solutes inside of
the cell is higher. If this water influx continues for a long period of time (with ineffective (or
absence of) volume regulation by the cell), the cell my lyse (burst) as the pressure builds up
inside to a magnitude greater than can be handled by the cellular membrane.
here are a number of ways in which red blood cells (and animal cells in general) cope with
changes in solute concentration on the outside of their membrane surfaces. There may be a
volume regulatory decrease (RVD) or increase (RVI) depending upon the concentration of the
solutes on the outside of the cellular membrane (Freedman, 1998). The response that is activated
by the swelling of the cells usually involves an increase in the K+/Cl- transporters (see figure 2)
in ducks, sheep, rabbits, and some other mammals (Freedman, 1998; Motais et al, 1997). The
swelling response may also trigger the formation of a channel (in which band 3 is involved) that
allows osmolytes such as taurine (and other small, organic, osmotically active solutes) to be
transported out of the cell (Freedman, 1998; Motais et al, 1997). The shrink activated response in
red blood cells involves the activation of Na+/K+/2 Cl- cotransporters (in general, and in the
case of the duck (Freedman, 1998)).
The molarity in plasma of NaCl is approximately 0.15M, therefore the concentration of 0.15M
NaCl treatment would be considered isosmotic to red blood cell plasma. The change in
concentration to 0.12 M NaCl would be a hypotonic condition, and the conditions of 0.21, 0.33,
0.157, and 1.05M NaCl would be hypertonic conditions.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The periodic table of the chemical elements (also known as the perio.pdf
1. The periodic table of the chemical elements (also known as the periodic table or periodic table of
the elements) is a tabular display of the 118 known chemical elements organized by selected
properties of their atomic structures. Elements are presented by increasing atomic number, the
number of protons in an atom's atomic nucleus. While rectangular in general outline, gaps are
included in the horizontal rows (known as periods) as needed to keep elements with similar
properties together in vertical columns (known as groups), e.g. alkali metals, alkali earths,
halogens, noble gases.
Periods
A period is a horizontal row in the periodic table. Although groups are the most common way of
classifying elements, there are some regions of the periodic table where the horizontal trends and
similarities in properties are more significant than vertical group trends. This can be true in the d-
block (or "transition metals"), and especially for the f-block, where the lanthanides and
actinides form two substantial horizontal series of elements.
Periodic trend for ionization energy. Each period begins at a minimum for the alkali metals, and
ends at a maximum for the noble gases.
Elements in the same period show trends in atomic radius, ionization energy, electron affinity,
and electronegativity. Moving left to right across a period, atomic radius usually decreases. This
occurs because each successive element has an added proton and electron which causes the
electron to be drawn closer to the nucleus. This decrease in atomic radius also causes the
ionization energy to increase when moving from left to right across a period. The more tightly
bound an element is, the more energy is required to remove an electron. Electronegativity
increases in the same manner as ionization energy because of the pull exerted on the electrons by
the nucleus. Electron affinity also shows a slight trend across a period. Metals (left side of a
period) generally have a lower electron affinity than nonmetals (right side of a period) with the
exception of the noble gases.
Hope this explains your daughter.... :)
