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.
The nucleus of every atom has positive charge because protons and neutrons of those atoms have positive charge.. PROTON which has positive charge is residing IN the nucleus, â¦ an ELECTRON, which has negative charge is to be 'found' around the nucleus in a socalled shell. 9 people found this useful.
