The approximate size of the nucleus of Ni (mass number-64) is_____
a) 3 fm
b) 4 fm
c) 5 fm
d) 2 fm
Nuclear sizes obey roughly the following empirical relation
: r=R0 A 1/3
where r is the radius of the nucleus
R0 is a constant whose value is equal to 1.25 fm (femo meters units)
A is atomic mass of element
