The radius of hydrogen atom, in its ground state, is of the order of

A

`10^(-8) cm`

B

`10^(-6) cm`

C

`10^(-5)` cm

D

`10^(-4)` cm

Text Solution

Verified by Experts

The correct Answer is:
A
`r_(n)=(in_(0) n^(2) h^(2))/(pi" me"^(2))=0.53 Å`
`=0.53xx10^(-10) m`
`0.53xx10^(-8) cm`
`=10^(-8)` cm
