TermDefinition
Atoms chemical element that has it's own unique type of particle.
Nucleus part of an atom that gives an element its identity.
Proton A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron.
Neutron A subatomic particle of about the same mass as a proton but without an electric charge, present on all atomic nuclei except those of ordinary hydrogen.
Atomic number number of protons in an element's nucleus.
Isotopes Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element
Atomic weight approximately equal to the sum of the number of protons and the number of neutrons in the nucleus.
Electrons particles having opposite electric charge from the protons.
