two
8
Q
The Atom’s Electron Configuration:
A
arrangement of electrons in an atom
9
Q
The 3 rules that govern electron configuration:
A
-Aufbau Principle
-Pauli’s Exclusion Principle
-Hund’s Rule
10
Q
Aufbau Principle:
A
electrons occupy positions of lowest energy
11
Q
Pauli’s Exclusion Principle;
A
no two e- are alike, two e- in smae orbital must have opp spins
12
