Bohr Model

Electrons live in “shells” that revolve around the nucleus of the atom
The first shell can hold 2 electrons
Every subsequent shell can hold 8 electrons
The last shell is known as the valence shell and is involved with all chemical reactions (bonds form by the sharing of electrons)

Heisenberg Uncertainty Principle
Suborbitals
Orbitals are clouds of probability where an electron might be found → an area where they are they may be


Rules of Suborbitals
Naming
To name the electron configuration, list every energy level, every orbital, and how many electrons are in each orbital
