Understand the structure of an atom: An atom consists of a nucleus and an electron cloud.
Identify the components of the nucleus: The nucleus contains protons and neutrons.
Recognize the location of protons: Protons are positively charged particles located in the nucleus of an atom.
Differentiate between the nucleus and other parts of the atom: The electron cloud surrounds the nucleus and contains electrons, which are negatively charged.
Conclude that protons are not found in the outer shell or atomic orbitals, but specifically in the nucleus of the atom.
