: Negatively charged particles that orbit the nucleus in specific regions called shells or orbitals. They are much smaller than protons and neutrons. Key Characteristics

: Particles with no charge, also found in the nucleus. They provide stability and contribute to the atom's mass. : Negatively charged particles that orbit the nucleus

: Positively charged particles located in the center of the atom (the nucleus). The number of protons determines the identity of the element. Hydrogen has 1 proton
