If first excitation potential of a hydrogen-like atom is `V` electron volt, then the ionization energy of this atom will be:

A

V electron volt

B

`(3V)/4` electron volt

C

`(4V)/3` electron volt

D

cannot be calculated by given information

Text Solution

Verified by Experts

The correct Answer is:
C
First excitation energy `=RhC(1/(1^(2))-1/(2^(2))) =RhC 3/4`
`:. 3/4 RhC =V e.v`
`:. RhC=(4V)/3 e.v.`
