Question:

Bohr atom model is invalid for:

Show Hint

The Bohr model is valid only for hydrogen-like atoms, where there is one electron orbiting the nucleus. It does not work for multi-electron systems or atoms that are fully ionized.

  • Hydrogen atom
  • doubly ionized helium atom
  • deuteron atom
  • singly ionized helium atom
  • doubly ionized lithium atom

The Correct Option is B

Solution and Explanation

Step 1: The Bohr model is applicable to hydrogen-like atoms, where there is a single electron in orbit around the nucleus. For other atoms with multiple electrons, the Bohr model fails to explain their behavior accurately. 
Step 2: In the case of a doubly ionized helium atom, the atom has no electrons, making the Bohr model invalid for such systems. Therefore, the Bohr model does not work for the doubly ionized helium atom.
