The sum of the number of neutrons and protons in an atomic nucleus Liquids or gases at room temperature. Some can be solid, but they melt at low temperatures. Heavy uncharged particles found within atomic nuclei Formed when one or more electrons are transferred from one metal to non-metal atom Atoms of the same element that have different numbers of neutrons The number of protons in the nucleus of an atom An attraction between a positive metal ion and the electrons surrounding it A chemical bond formed when non-metal atoms share electrons A grouping of electrons surrounding the nucleus of an atom An atom's dense central core, containing protons and neutrons. Heavy positively charged particles found within atomic nuclei. The force that holds atoms together Very high melting and boiling points, insoluble in water and not good electrical conductors Negatively charged particles, with very small mass, found outside the nucleus From low to high melting and boiling points, insoluble in water and very good electrical conductors Very high melting and boiling points, soluble in water and good electrical conductors in solution or molten
