The total energy of the electron in the hydrogen atom in the ground state is `- 13.6 eV`. The `KE` of this electron is.

A

`13.6 eV`

B

zero

C

`- 13.6 eV`

D

`6.8 eV`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `because KE = (1)/(2) mv^2 = (Ze^2)/(2 r) , TE = - (Ze^2)/(2 r)`.
