For which one of the following, Bohr model is not valid?

For which one of the following, Bohr model is not valid?

Options

  1. ASingly ionised helium atom (He+)\left({He}^{+}\right)
  2. BDeuteron atom
  3. CSingly ionised neon atom (Ne+)\left({Ne}^{+}\right)
  4. DHydrogen atom

Correct answer

C. Singly ionised neon atom (Ne+)\left({Ne}^{+}\right)

Step-by-step 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.
