If the energy of electron in H atom is given by expression `- 1312/ n^(2) kJ "mole"^(-1)` then the energy required to excite the electron from ground state to second orbit is

A

328 kJ

B

656 kJ

C

984 kJ

D

1312 kJ

Text Solution

Verified by Experts

The correct Answer is:
C
`Delta E =1312 [(1)/(1^(2))-(1)/(2^(2))]kJ mol^(-1)`
`= 1312 xx (3)/(4) = 984 kJ mol^(-1)`
