Atoms are made up of smaller components called atomic (or subatomic) particles. Atoms consist of electrons that are bound to a tiny nucleus. 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 ... The two subatomic particles are the protons and neutrons. The atomic mass is essentially equal in magnitude to the protons and neutrons as the mass of an ... Jan 29, 2023 ... A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist ... Nov 28, 2023 ... For example, carbon-12 is a nuclide of carbon with 6 protons and 6 neutrons. This image shows how an atom is characterized in the periodic table ... All matter, with the exception of sub-atomic particles, is made up of atoms that contain an outer shell of electrons and an inner nuclear core.
