THE ONE AND ONLY BOHR MODEL!

-Atoms are electronically neutral

-Two different models can be used to describe electron configuration:

1) Energy level models

2) Bohr Model

-Electrons occupy orbitals:

1) 2e in the first orbital

2) 8e in the second orbital

3) 8e in the third orbital

*2 and 3 are an octet

ARGON - it would look something like this:

Chlorine - it would look something like this:

ORBITAL SHAPES

-Atomic orbitals each have a specific name and shape

2s is the same as 1s but it bigger in size

Hybridized Orbitals

-The first of the Bohr levels is the 1st orbital and it holds 2e

- The second level contains 2s, 2px, 2py, 2pz orbitals.

- They combine (hybridize) to form one 2sp3 orbital.
