For which one of the following, Bohr model is not valid?
  1. Singly ionised helium atom He+
  2. Deuteron atom
  3. Singly ionised neon atom Ne+
  4. Hydrogen atom

Solution

Bohr's model is valid only for the single electronic systems. Therefore, it will not be valid for a singly ionised neon atom as it has more electrons.
