Question

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: [R= 1.33 × 10^-13 cm] [Answer in nearest integer]

Question Explanation: Calculate the radius of the nucleus ( $r$ ).

Concept:

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

Solution:

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

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

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

$r = 3.99 \times 1 0^{- 13} c m$

$r \approx 4 \times 1 0^{- 13} c m$
