When we say energy levels in an atom are discrete, we mean that their energy levels are well defined and
A)separate from one another.
B)separated by equal energy increments.
C)continuous.
D)private.

Question

Quizplus · Accepted Answer

Discrete energy levels mean that the energy levels in an atom are separate from one another and have well-defined energy values. There are no intermediate energy levels between these well-defined levels. This is in contrast to continuous energy levels, which represent a continuous spectrum of energy values with no distinct separation between them. Therefore, the correct answer is A.
