Question

Pick out the wrong statement about Bohr atom model

• A. Orbit of the electron is circular
• B. Model is applicable only for single electron systems
• C. Orbits of the electron are non-radiating
• D. Angular momentum of electron in an orbit is quantized
• E. Model is applicable for many electron systems also

Hint:

Bohr model is mainly valid for one-electron systems like H, He\(^+\), Li\(^{2+}\), etc.

Answer 1

Answer: (E)

Bohr model assumes:

• electrons move in circular orbits,
• these orbits are stationary and non-radiating,
• angular momentum is quantized.

Bohr model works well only for: \[ \text{hydrogen and hydrogen-like one-electron species} \] It does not successfully explain many-electron atoms. So the wrong statement is: \[ \boxed{(E)\ \text{Model is applicable for many electron systems also}} \]
