The simple Bohr model is not applicable ...

The simple Bohr model is not applicable to `He^(4)` atom because

A

`He^(4)` is an inert gas.

B

`He^(4)` has neutrons in the nucleus

C

`He^(4)` has one more electron.

D

electrons are not subject to central forces

Text Solution

Verified by Experts

The correct Answer is:
C, D
Bzohr.s basic atomic model is for an atom having single electron.
`rArr` Thus, option (C) is correct.
He nucleus has two protons but they do not lie at the same position and so electrostatic attractive force on electron is not pointing towards single central position and so it does not remain central force. Hence option (D) is correct.
