1
New cards

what is the aufbau principle

electrons occupy orbitals from lower principal energy levels before occupying orbitals at higher principal energy levels

2
New cards

what is the pauli exclusion principle

a maximum of 2 electrons can occupy a single orbital, but only if the electrons have opposite spin

3
New cards

what is hund’s rule?

all electrons with the same energy must occupy each equal-energy orbital before additional electrons with opposite spin can occupy the same orbitals

4
New cards

how do you determine the maximum number of electrons per each principal energy level?

use the formula 2n² [ 1st energy level - 2(1)²=2 ] [ 2nd energy level - 2(2)²=8 ] [3rd energy level - 2(3)²=18 ] [ 4th energy level - 2(4)²=36 ]

5
