Answer 1

Mass Number:-

● The total number of protons and neutrons in an atom.

Atomic Number:-

● The number of protons that a chemical element has in its centre (nucleus).

Chlorine:-

● The relative atomic mass of chlorine is 35.5 rather than a whole number. This is because chlorine contains two different isotopes, chlorine-35 and chlorine-37. The table shows the mass numbers and abundances of the isotopes of copper in a naturally-occurring sample.
