For which one one of the following bohr model is not valid

A

Hydrogen atom

B

Singly ionised helium atom `(He^(+))`

C

Deuteron atom

D

Singly ionised neon atom `(Ne^(+))`

Text Solution

Verified by Experts

The correct Answer is:
D
Bohr model is only valid for single electron species. Singly ionised neon atom has more than one electron in orbit. Hence, Bohr model is not valid
