Question

Calculate the approximate radius of the 31P nucleus (assume r0 = 1.3x10-15 m).

Answer 1

4.08 x 10⁻¹⁵ m

Step-by-step explanation:

r₀ = constant of proportionality = 1.3 x 10⁻¹⁵ m

r = radius of the nucleus 31P = ?

A = mass number of the nucleus 31P = 31

Radius of the nucleus is given as

`r=r_(o)A^{(1)/(3)}`

Inserting the values

`r=(1.3* 10^(-15))(31)^{(1)/(3)}`

`r=(1.3* 10^(-15))(3.14)`

r = 4.08 x 10⁻¹⁵ m
