Question

Drawback of Neil's Bohr's atom model

Answer 1

1) According to Bohr , the radiation results when an electron orbit , but how this radiation occurs is not explained by Bohr .

2) He could not explain sophisticated spectroscopy techniques .

3) Bohr's model was two dimensional where an atom is three-dimensional .

4) He could not explain for Zeeman effects ( magnetic effect ) on the line spectra .

5) He is unable to explain of stark effect ( electric effect ) on the line spectra .

Answer 2

Drawbacks of Bohr's Model:

Drawbacks of Bohr's Model:It was primarily for hydrogen atom. It couldn't elaborate spectra of multi-electron atoms. Wave nature of electron was not justified by the model (inconsistent with the de Broglie's hypothesis of dual nature of matter) It didn't illustrated molecules making process of chemical reactions.
