The potential energy of the electron present in the ground state of ` Li^(2+)` ion is represented by :

A

`(+3e^(2))/(4 pi epsi_(0)r)`

B

`(-3e)/(4 pi epsi_(0)r)`

C

`(-3e^(2))/(4 pi epsi_(0)r^(3))`

D

`(-3e^(2))/(4 pi epsi_(0)r)`

Text Solution

Verified by Experts

The correct Answer is:
D
In S.I units the `P.E = (-Ze^(2))/(4 pi epsi_(0)r)`. For `Li^(2+)` , Z = 3
`therefore P.E = (-3e^(2))/(4 pi epis_(0)r)`
