How are the radius of nucleus r and mass number (A) related to each other?

Text Solution

Verified by Experts

The volume of the nucleus is directly proprtional to the number of nucleons (mass number) constituting the nucleus.
`(4)/(3)pir^(2)propA" " Where" "R rarrradius`
`R propA^(1//2)" "Ararr"mass number"`
`R=R_(0)A|1//3`
