The ionization energy of H atom is x kJ....

The ionization energy of H atom is x kJ. The energy required for the electron to jump from `n = 2` to `n = 3` will be:

A

`5x`

B

`36 x//5`

C

`5x//36`

D

`9x//4`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_("ionisaton") = -E_1`
`E_1 =-x E_2 = - (x)/(4) E_(3) = - (x)/(9)`
`Delta E= (-x)/(9) - (x)/(4) = (x)/(4) - (x)/(9) = (5 x)/(36)`
