Question

Which of the following is wrong for Bohr model?

• A. It establishes stability of atom
• B. It is contradicted with Heisenberg uncertainity principle.
• C. It explain the concept of spectral lines
• D. $e^{-}$ behave as particle & wave

Answer 1

The correct option is D $e^{-}$ behave as particle & wave

(1) Bohr's model accounts for the stability of atoms because the electron cannot lose more energy than it has in the smallest orbit.
(2)according to the uncertainty principle, it is impossible to determine simultaneously the exact position and the momentum (or velocity) of a microscopic particle-like electron. thus, Bohr's model contradicts Heisenberg's uncertainty principle.
(3) Spectral lines were the result of light being released or absorbed as an electron moved from one orbit to another in the atom. As the electron relaxed it would release energy.
(4)Electron as wave and particle was explained by de- Broglie.
Hence answer is the D option
