Chapter 28, Problem 10Q

To determine

In which model of the hydrogen atom, the electron spends more time near the nucleus

Answer to Problem 10Q

Solution:

In the quantum mechanical model, the electron spends more time near the nucleus.

Explanation of Solution

In the Bohr model, the electrons are revolving around the nucleus from a fixed distance from the nucleus. So, it cannot move from these fixed orbits.

In the quantum mechanical model, the electrons are supposed to stay in “electron clouds” which is the area where the electrons are supposed to stay.

In the higher levels, the electrons will spend less time since the atom becomes unstable.
