Atoms and Nuclei question

2020 · Q122

NEETPhysicsAtoms and NucleiMCQ+4 / −1
For which one of the following, Bohr model is not valid?
  1. A
    Singly ionised helium atom (He+)
  2. B
    Deuteron atom
  3. C
    Singly ionised neon atom (Ne+)
  4. D
    Hydrogen atom
View written solutionFree

Correct answer: C

Singly ionized neon has electron count more than one. Bohr's model is valid for atoms of single electron. So option (c) is not valid.
