Recall the basic structure of an atom, which consists of a nucleus at the center and an electron cloud surrounding it.
Understand that the nucleus contains two types of subatomic particles: protons and neutrons.
Recognize that electrons are located in the electron cloud, which is the region around the nucleus.
Note that neutrons are not found in the electron cloud or attached to electrons; instead, they reside in the nucleus along with protons.
Therefore, the correct location of neutrons is inside the nucleus of the atom, together with protons.
