Quantum mechancial model of atom is the ...

Quantum mechancial model of atom is the picture of the structure of the atom which emerges from the application of the Schrddot(o)dinger equation to atoms. Which of the following is the incorrect feature of the euantum mechanical model of atom?

A

The energy of free electrons is quantized.

B

The existance of quantized enegry levels is the direct result of the wave-like properties of electron and are allowed solutions of the Schrddot(o)dinger wave equation.

C

We talk of only the proabability of finding the electron at different points in an atom as the path of an electron in an atom can never be determined or known accurately in accordance with Heisenberg's uncertainty principle.

D

To distinguish the quantum mechanical description form Bohr's model, we speak of an atomic orbital or just orbital, rather than an orbit. An orbital can be though of as the wave function `(psi)` of an electron in an atom.

Verified by Experts

The correct Answer is:
A

The enegry of electrons is quantized (i.e., can only have certain specific values) only when the electrons are bound to the nucleus in atoms.
