Minimum excitation potential of Bohr's first orbit in hydrogen atom is ...... eV

A

13.6

B

3.4

C

10.2

D

3.6

Text Solution

Verified by Experts

The correct Answer is:
C
When electron transits from orbit n = 1 to n = 2 then it get minimum excitation energy.
Minimum excitation energy
`=(13.6)/(2^(2))-(-(13.6)/(1^(2)))`
`=-(13.6)/(4)+13.6`
=10.2 eV
