Verified step by step guidance1
Understand the structure of an atom: An atom consists of a nucleus and an electron cloud. The nucleus is the central part of the atom.
Identify the particles in the nucleus: The nucleus contains protons and neutrons. These are collectively known as nucleons.
Differentiate between protons, neutrons, and electrons: Protons are positively charged particles, neutrons have no charge, and electrons are negatively charged particles that orbit the nucleus.
Recognize that electrons are not found in the nucleus: Electrons are located in the electron cloud surrounding the nucleus, not within the nucleus itself.
Conclude that the particles found in the nucleus are protons and neutrons, as electrons are located outside the nucleus.
