Question 14

How to find the average atomic mass

Answer 14

(Mass)(%) + (Mass)(%)
Dived by 100

Question 15

Ionization energy

Answer 15

Energy it takes to remove an electron
Atom + energy => cation + Ie

Question 16

Electron Affinity

Answer 16

Energy change when an atom gains an electron
Atom + e => anion + energy
