Question

Composition of the nuclei of two atomic species X and Y are given
X Y
Protons = 6 6
Neutrons = 6 8
Give the mass numbers of X and Y. What is the relation between the two species?

Answer 1

Mass number is equal to the sum of the protons and neutrons...

Explanation:

So, mass number for X = 6+6

= 12

and for Y = 6+ 8

= 14

= protons and neutron are present inside the nucleus and they are collectively known as nucleons...
