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