8th Grade Integrated Science Chapter 8 Lesson 1 on Electrons and Energy Levels. This lesson gives a brief introduction of the periodic table, periods, and groups. There is an introduction to metals, nonmetal, and metalloids. This also introduces electrons, energy levels, and the basic idea of bonding.

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.

1. Atoms
Their structure and the properties
of elements
An element smallest posible piece…
Miss Sofia Paz
2. First: Different elements or compounds have different properties:
States (luquid, solid, gas, plasma) this properties depend on the atoms of the elements!
MADE UP OF
SUBATOMIC
PARTICLES:
-PROTONS(+)
-NEUTRONS
-ELECTRONS(-)
ATOM:
Smallest possible piece of
an element (without loosing
their properties)
3. The attraction of the
negatively charged
electrons and the
positively charged
protons keeps the
electrons close to
the nucleus.
4. How this subatomic particles form an ATOM?
-NUCLEOUS: NEUTRONS, PROTONS(+),
-CLOUD OF ELECTRONS (-)
The attraction of the
negatively charged
electrons and the
positively charged
protons keeps the
electrons close to
the nucleus.
Electrons have less
mass than neutrons
and protons.
5. NOT constantConstant
ATOMIC NUMBER (Z)( NUMBER OF PROTONS)
# of # of
The number of
protons is constant
in each element
The atom is
electrically neutral,
positive charges are
balanced with
the negative charges.
NO two
elements have
the same
atomic number
the number of protons = the Atomic Number(Z)
6.
7. ISOTOPES (when the number of neutrons change)
Alternate forms of elements (always same proton number but
different neutron number)
Why C14, C13, C12??? Is the NUCLEAR NUMBER: NUMBER OF
PROTONS + NUMBER OF NEUTRONS
8. RADIOACTIVE ISOTOPE:
HOMEWORK FOR NEX CLASS! What are radioactive
isotopes and What uses does they have?
CONCEPT :CHEMICAL PROPERTIES ARE BASED ON STRUCTURE OF ATOMS
9. ElECTRONS AND REACTIVITY:
Electrons properties: -amount of energy
-how thigly they are held by protons
Depending on this properties electrons belong to differents energy
leves:
I energy level can hold up to 2 electrons
II energy level can hold up to 8 electrons
III energy level can hold up to 18 electrons
HOW DOES ATOMS STRUCTURE DETERMINE HOW IT REACTS??
10.
11. CONCEPT :CHEMICAL PROPERTIES ARE BASED ON STRUCTURE OF ATOMS
I energy level :2 electrons
II energy level: 8 electrons
III energy level : 18 electrons
