Which of the following best describes what an electron cloud represents in an atom?
A
The fixed path that electrons follow around the nucleus
B
The area where the nucleus is located
C
The total number of protons and neutrons in the atom
D
The region around the nucleus where electrons are most likely to be found
Verified step by step guidance1
Understand that the electron cloud is a concept used to describe the behavior and location of electrons in an atom.
Recall that electrons do not move in fixed paths like planets around the sun; instead, their positions are described by probabilities.
Recognize that the electron cloud represents the region around the nucleus where electrons are most likely to be found based on these probabilities.
Eliminate options that describe fixed paths, the nucleus location, or the composition of the nucleus (protons and neutrons), as these do not relate to the electron cloud.
Conclude that the electron cloud best describes the area around the nucleus where electrons are most likely to be found.
