Bohr Model
Often referred to as the "planetary" model
This is because it models the electrons as orbiting the nucleus like the planets orbit the sun.
4
Bohr Model-INCORRECT
We have since discovered that electrons do not behave like planets orbiting the sun

BUT... Bohrs model is very helpful for showing the # of energy levels & ...
just look at the PERIODS (rows)!!!

Multiple Choice
9
AND the possible # of electrons found in each level
2. 8. 18. 32. 32. 18. 2
aren't you glad you only have to know the first 4 levels & the OCTET RULE!!!!
10
Multiple Choice
11
The OCTET (8) Rule-
Atoms tend to form compounds that give them EIGHT valence electrons and thus the electron configuration of a noble gas.
12
Multiple Choice
13
An exception to an octet
of electrons is in the case of the first noble gas, helium, which only has two valence electrons.
14
The VALANCE electrons are the electrons in outer most shell/level/ring.
15
The VALANCE electrons are REALLY important because
they determine how reactive an element is...
16
You can determine how many VALENCE electrons atoms have by looking at the group #s of the main electrons
