Question

The basis of quantum mechanical model of an atom is :

• A. angular momentum of electron
• B. quantum numbers
• C. dual nature of electron
• D. black body radiation

Answer 1

The correct option is C dual nature of electron

The quantum mechanical model of atom is based upon the dual nature of electron, i.e., the electron is not only a particle but has a wave character.

The wave character of electron has particle significance since its wavelength is easily observed in electromagnetic spectrum.

Hence the correct option is C.
