no two electrons can have the same set of 4 quantum numbers
2
Q
Afbau Principle
A
describes how to fill an orbital diagram with electrons; from the bottom up
3
Q
Hund’s Rule
A
in the p, d, and f orbitals, they are filled with one electron each with the same spin, then they are paired with electrons spinning the opposite direction

Q
What is inaccurate about Bohr’s model of the atom?
A
- it did not explain or show the shape or path of travel of the electrons
- it falsely assumed that electrons travel in perfect orbitals
- it could only explain hydrogen & not more complex atoms
