Negatively charged particles, with very small mass, found outside the nucleus The number of protons in the nucleus of an atom An atom's dense central core, containing protons and neutrons. A table that classifies elements by their physical and chemical properties; rows are called periods; columns are called groups; Two or more non-metal atoms held together by covalent bonds Liquids or gases at room temperature. Some can be solid, but they melt at low temperatures. A grouping of electrons surrounding the nucleus of an atom The sum of the number of neutrons and protons in an atomic nucleus The force that holds atoms together An attraction between a positive metal ion and the electrons surrounding it Heavy positively charged particles found within atomic nuclei. Heavy uncharged particles found within atomic nuclei
