Bohr's theory cannot be applied on:
Correct answer: B. H+
- A. H
- B. H+
- C. He+1
- D. Li+2
Explanation
Bohr's theory is only applicable to hydrogen-like species containing one electron only. As H, He1+ and Li2+ all have one electron each, hence Bohr's theory is applicable on them. But H+ has 0 electrons and that is the reason Bohr's theory is not appliable on it.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
