Assuming atom to be a sphere, the radius of atom would be [if the apparent volume of atom of a metal is `1.23xx10^(-23)mL`]

Options

A. `1.401 Å`
B. `1.942 Å`
C. `1.642 Å`
D. `1.541Å`

Answer

A

Explanation

`V=4/3 pir^(3)`
`(3V)/(4pi)=r^(3)rArrr=((3V)/(4pi))^(1//3)`
`logr=1/3 log[(3V)/(4pi)]`
`log r=1/3 log[(3xx1.23xx10^(-23))/(4xx3.14)]`
