Recall the basic structure of an atom, which consists of a nucleus and an electron cloud surrounding it.
Understand that the nucleus is the central part of the atom and contains protons and neutrons.
Recognize that protons are positively charged particles located inside the nucleus.
Know that the electron cloud is the region around the nucleus where electrons, which are negatively charged, are found.
Therefore, protons are located in the nucleus, not in the electron cloud, valence shell, or outermost energy level.
