A chemical bond formed when non-metal atoms share electrons Very high melting and boiling points, soluble in water and good electrical conductors in solution or molten An atom's dense central core, containing protons and neutrons. An attraction between a positive metal ion and the electrons surrounding it Very high melting and boiling points, insoluble in water and not good electrical conductors Heavy uncharged particles found within atomic nuclei Negatively charged particles, with very small mass, found outside the nucleus 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 A table that classifies elements by their physical and chemical properties; rows are called periods; columns are called groups; Charged atoms 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 From low to high melting and boiling points, insoluble in water and very good electrical conductors The number of protons in the nucleus of an atom The smallest unit of matter that constitutes a chemical element.
