Verified step by step guidance1
Understand the structure of an atom: An atom consists of a nucleus and an electron cloud. The nucleus contains protons and neutrons, while the electron cloud contains electrons.
Identify the role of neutrons: Neutrons are subatomic particles with no electric charge, and they reside in the nucleus of an atom along with positively charged protons.
Differentiate between the nucleus and other parts of the atom: The nucleus is the dense central core of the atom, whereas the atomic orbitals and electron cloud refer to regions where electrons are likely to be found.
Recognize that atomic orbitals and electron clouds are associated with electrons: These terms describe the regions around the nucleus where electrons are likely to be found, not neutrons.
Conclude that neutrons are located in the nucleus: Since neutrons are part of the nucleus, they are not found in atomic orbitals, the electron cloud, or the outer shell.
