Question

How is the radius of a nucleus related to its mass number?

Answer 1

mass = number of protons+ number of neutron.
so nucleus contains protons and neutrons So by this way it's related to mass number.

Answer 2

Answer:

Radius of nucleus is directly proportional to the mass number(no. of nucleons ).

Mathematically ,

R=Ro A to the power 1/3

where,

R=Radius of nucleus

Ro= constant

A=mass number
