Question

What does it mean to say that the energy of the electrons in an atom is quantized?

a) Electrons can have any energy value.

b) Energy levels of electrons are restricted to specific values.

c) Electrons have continuous energy levels.

d) Electrons have infinite energy levels.

Answer 1

Quantized energy means that electrons in an atom can possess only certain discrete energy values, restricted to specific levels.

Step-by-step explanation:

Quantized energy means that the electrons in an atom can possess only certain discrete energy values. These values are restricted to specific levels and are not continuous. The energy levels of electrons are labeled with a principal quantum number, usually denoted by 'n', which represents the shell number or the location of the energy level.
