A subatomic particle is a unit of matter or energy that's the fundamental makeup of all matter. According to modern atomic theory, an atom has a nucleus, which is its center, or core. The nucleus contains subatomic particles: protons and neutrons. Protons are positively-charged particles. Neutrons are neutral particles.
More specifically, the atom will have a positive net charge if it has more protons in its nucleus than electrons surrounding its nucleus a negative net charge if it has more electrons surrounding its nucleus than protons in its nucleus no net charge if it has equal numbers of protons and electrons When an atom carries a positive net charge, it forms a cation, or positively charged ion. Likewise, when an atom carries a negative net charge, it forms an anion, or negatively charged ion. In your case, the atom is said to contain. eight protons. nine neutrons â they do not influence the net charge of the atom.
