The ionization potential for second `H`e electron is

A

13.6eV

B

27.2eV

C

54.4eV

D

100eV

Text Solution

Verified by Experts

For a one -electron orbital, the potential energy of that orbital is opposite in sign to the ionization energy from that orbital.
`:.` Here I.E. `=(13.6xx2^(2))/(1^(2))`
`=54.4eV`
