-atoms are electrically neutral
-there are 2 models that can be sued to describe electron configuration:
1.) energy level model
2.) bohr model
-electrons occupy shells which are divided into orbitals:
- 2e- in the frist orbital
- 8e- in the second orbital
- 8e- in the third orbital
-atomic orbitals each ahve a specific name and shape
hybridized orbitals:
-the first of the bohr levels is the first orbital and it holds 2e-
-the 2nd contains the 2s, 2px, 2py, 2pz orbitals, they combine (hybridize) to form one 2sp3 orbital
