The nuclear radius of 
is 3 × 10 –15 m. What is the nuclear radius of 
?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
Sol. Mass number of 
nucleus, A 1 = 16
Nuclear radius of 
nucleus,R 1 = 3 × 10 –15 m
or R 1 = 3 fermi
Mass number of 
nucleus, A 2 = 205; Nuclear radius of 
nucleus, R 2 = ?
Nuclear radius is given by R = R 0 A 1/3 For 
, R 1 = R 0 A 1
1/3 For 
R 2 = R 0 A 2
1/3 Dividing, 
= 
or R 2 = R 1 × 
= 3 × 
fermi = 7.02 fermi
