Where is a neutron located in an atom?

A neutron is located in the nucleus of an atom, which is at the center and serves as the core that contains most of the atom's mass. The nucleus itself is made up of protons and neutrons, which are collectively known as nucleons. Neutrons play a crucial role in contributing to the stability of the nucleus, as they help to offset the repulsive forces between the positively charged protons.

The incorrect options refer to locations that do not accurately reflect where neutrons are found. The electron cloud is where electrons are located, and it encompasses the region outside the nucleus; neutrons are not part of this electron cloud. Similarly, being outside the nucleus or among electrons is not consistent with the established atomic structure. Neutrons do not exist freely in these regions; instead, they are tightly bound within the nucleus alongside protons.
