Today in Class we learned how to draw out Bohr models and Energy levels, we went over a few diagrams.

Bohr Model

- Atoms are electrically neutral= it is equal
- Two different models can be used to describe electron configuration
- 1)Energy level 2) Bohr Model
- Electrons occupy shells which are divided into orbitals.( 2, 8, 8 )
- 2 e- in the first orbital
- 8 e- in the second orbital-octet
- 8 e- in the third orbitaloctet

Orbital shapes
- Atomic orbitals each have specific name and shape
- 1s


Hybridized orbitals
- The first of the bohr levels is the 1st orbital and it holds 2e-
- The second level contains the 2s, 2px, 2pv, 2pz orbitals. They combine (hybridize) to form on 2sp3 orbital

Other hybridized orbitals
- There are many different types of hybrized orbitals

FOR HOMEWORK: we are to complete the page in the package titled " ELECTRON ENERGY LEVEL DIAGRAMS FOR ATOMS"
