The radius of certain orbit of H-atom is 2.12 A. Then the energy of that energy level is

A

`-(13.6)/(4)` eV/atom

B

`(2.18xx10^(-18))/(4) ` J/atom

C

`(-1312(/(4)` KJ/atom

D

`(-1313.6)/(4)` Kcal/mole

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
The radius of certain orbit of H-atiom is `2.12 A^@` . Then the energy of that energy level is
`(-13.6)/(4) `eV/atom ,` (-2.18 xx 10^(-18))/(4)` J/atom
`(-313.6)/(4) `Kcal/mole
