Question

Which of the following ideas are included in the quantum mechanical model of the atom?

I. Electrons are likely to be located in s, p, d, and f orbitals;
II. The differences between energy levels are quantized amounts;
III. The positive charge of the nucleus eventually pulls electrons into the center of the atom.
A) I and II
B) I and III
C) II and III

Answer 1

The correct option is: A) I and II

Step-by-step explanation:

The quantum mechanical or the wave mechanical model explains the wave-like nature of the subatomic particle called electrons and the existence of quantized electronic energy levels.

It also describes the atomic orbital as the space around the nucleus, where the probability of finding an electron is maximum. Thus electrons of an atom occupy a set of s, p, d and f atomic orbitals.
