Atomic Mass

13

How do we calculate Atomic Mass

Protons + Neutrons.

14

Protons + Neutrons is the calculation for

Atomic Mass

15

What are Isotopes

They are elements which have the same number of Protons but different numbers of neutrons

16

Elements which have the same number of Protons but different numbers of neutrons are known as

Isotopes

17

What is Quantum Theory of Energy

Electrons that are limited to certain energy levels
