The radius of nucleus ( r ) is related to its mass number ( A ) : as

$r = R_{0} (A)^{1/3}$

The radius of nucleus of an atom which has 14 neutron and 13 electron will be $x \times 1 0^{- 13}$ cm.

x is: [R₀= 1.33 × 10^-13 cm] [Answer in nearest integer]

Question Explanation:

Calculate radius of nucleus (r)

$C o n ce pt :_{r = R_{0} (A)^{1/3}}$

$Solution:_{r = R_{0} (A)^{1/3}}$

$= 1.33 \times 1 0^{- 13} \times (27)^{1/3}$

$= 1.33 \times 1 0^{- 13} \times 3$

$= 3.99 \times 1 0^{- 13} cm \approx 4 \times 1 0^{- 13} cm$
