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. Electrons are found in the electron cloud surrounding the nucleus.
Define protons: Protons are positively charged particles found in the nucleus. They determine the atomic number of an element.
Define neutrons: Neutrons are neutral particles, meaning they have no charge, and are also located in the nucleus. They contribute to the atomic mass but do not affect the charge.
Recognize the role of electrons: Electrons are negatively charged particles that orbit the nucleus in various energy levels or shells, and are not part of the nucleus.
