Verified step by step guidance
1
Understand that an atom is composed of three main types of subatomic particles: protons, neutrons, and electrons.
Protons are positively charged particles found in the nucleus of an atom. They contribute to the atomic number and identity of the element.
Neutrons are neutral particles, also located in the nucleus, and they contribute to the atomic mass but not the charge.
Electrons are negatively charged particles that orbit the nucleus in various energy levels or shells. They are much lighter than protons and neutrons.
Recognize that photons and neutrinos are not components of an atom. Photons are particles of light, and neutrinos are subatomic particles that are not part of the atomic structure.
