Verified step by step guidance1
Understand that energy levels in an atom refer to the specific regions around the nucleus where electrons are likely to be found. These are also called electron shells or orbitals.
Recall that nucleons (protons and neutrons) are located in the nucleus of the atom and do not occupy energy levels or shells.
Recognize that protons are positively charged particles in the nucleus and are not part of the energy levels.
Know that neutrons are neutral particles also located in the nucleus and do not occupy energy levels.
Conclude that electrons, which are negatively charged particles, are the ones found in the energy levels of an atom.
