This document discusses atomic structure and subatomic particles. It defines key terms like atomic number, mass number, isotopes, ions, and radioactivity. It explains that atoms are most stable when their ratio of neutrons to protons falls within a specific range, called the "band of stability." Atoms outside this band, especially very large atoms, tend to be radioactive as they decay toward more stable configurations.
The document discusses atomic theory and the structure of atoms. It explains that all matter is made up of atoms, which are the smallest particles of elements that can exist. Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons. The number of protons determines the element, while the number of neutrons can vary between isotopes of the same element. Chemical bonds form when atoms share or transfer electrons to fill their valence shells. This allows the formation of compounds with properties different from their constituent elements.
The document discusses a person's holiday trip to San Francisco. They traveled there by plane and the weather was sunny and hot. While there, they went canoeing and horseback riding. They enjoyed the trip and went with their family. They stayed in San Francisco for a week in early July.

Physical science 4.1 : Development of Atomic TheoryChris Foltz
Democritus was one of the first to propose the idea of atoms in 440 BCE, suggesting that matter is made up of tiny indivisible particles called atoms. In the early 1900s, experiments led scientists to develop more accurate models of the atom. Rutherford discovered the nucleus in 1909 by firing positively charged particles at a gold foil and observing some particles deflecting, indicating a small, dense nucleus. Bohr then proposed in 1913 that electrons orbit the nucleus in distinct energy levels. The modern atomic theory describes the regions where electrons are likely to be found as electron clouds.
This document summarizes the development of atomic theory over time from ancient Greek philosophers to modern theory. It describes the key contributions of thinkers such as Democritus, Dalton, Thomson, Rutherford, Bohr, Schrodinger, and Chadwick. Their successive models proposed that atoms are small particles that join to form matter (Democritus), contain electrons and a nucleus (Thomson, Rutherford), have electrons in fixed orbits around the nucleus (Bohr), exist as electron clouds (Schrodinger), and are composed of protons, neutrons, and electrons (modern theory).
This document outlines several trends that impact society including political, technological, institutional, ecological, socio-cultural, economic, national, regional, global and local trends. These trends shape the action of governing, the physical and social setting where people live, and civilization and demographics.
The document summarizes eight pamphlets attacking Jose Rizal's novel Noli Me Tangere and one pamphlet defending it. It also provides details about Rizal's time in Calamba, including the death of his sister and false accusations against him. Finally, it outlines some of Rizal's findings submitted against the Dominican owners of the hacienda in Calamba, including arbitrary rental increases, lack of contributions to the town, dispossessing tenants, and forced land sales when rent couldn't be paid.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

quantum number increases
the positive charge on the nucleus increases by one proton
Ionization Energy
-The ionization energy tends to increase as atomic number
increases in any horizontal row or period.
Electron Affinity
-The attraction of an atom for an electron.
-The general trend as you go down a column is a decreasing
tendancy to gain electrons.
- As you go across a row there is also a trend for a greater
attraction for electrons.
Chemical Bonding
Chemical bond
-is a mutual electrical attraction between the nuclei and valence
electrons of different atoms that binds the atoms together
Valence Electrons -A Valence electron is an electron in the
outer shell of an atom which can combine with other atoms to
form molecules
Bond
– valence electrons rearranged to make atom more stableWay
they are rearranged depends on type of bond.
Types of chemical bonding
Ionic bonding
- chemical bonding that results from the electrical attraction
between large numbers of cations and anions.
-metal-nonmetal
In forming compounds, atoms tend to gain or lose
electrons in order to achieve the electron configuration
of a noble gas
Key Concept Atoms of metals lose their valence electrons.
Atoms of some nonmetals ten to gain electrons or to share
with other nonmetallic elements to achieve a complete
octet
3. Formation of Cations -When an atom loses an electron it
produces a positively charged ion, or a cation. The most
common cations are those produced by the loss of valence
electrons from metal atoms. Electron–Dot Structures for
Ions Remove electrons for cations
Formation of Anion -The gain of negatively charged
electrons by a neutral atom produces an anion.
Covalent bonding
- results from the sharing of electron pairs between two atomsIn
purely covalent bond, electrons shared equally between two
atoms.
METALLIC BONDING
- metallic bonding usually occurs in metals, such as copper.
- The valence electrons of these atoms are free to move about
the piece of metal and are attracted to the positive cores of
copper, thus holding the atoms together.
Lewis dot Structure
-the structure of carbon and its compound can be expressed
using the Lewis-dot structure This system identifies how the
atoms that compose a molecule of a specific compound are
attached (bonded) to one another and (to some extent) oriented
in space
