Question 5

Shielding

Answer 5

Electrons in lower energy atomic orbitals reduce the electrostatic attraction between the protons on the nucleus and the electrons in the higher energy atomic orbitals

Question 6

Pauli exclusion principle

Answer 6

No two electrons can have the same set of quantum numbers

Question 7

Hund’s rule

Answer 7

Electrons will fill the same energy level orbitals to yield the maximum number of unpaired spins

Question 8

Aufbau principle

Answer 8

Start at the lowest energy level, for a ground state electron configuration all electrons should be at the lowest possible energy.

Question 9

Electron configuration

Answer 9

how the electrons are distributed among the various atomic orbitals

Question 10

Diamagnetic

Answer 10

Substances do not contain net unpaired spins and are slightly repelled by a magnet

Question 11

Paramagnetic

Answer 11

Substances are those that contain net unpaired spins and are attracted by a magnet
