Some can be solid, but they melt at low temperatures. The force that holds atoms together Charged atoms Negatively charged particles, with very small mass, found outside the nucleus An attraction between a positive metal ion and the electrons surrounding it Two or more non-metal atoms held together by covalent bonds An atom's dense central core, containing protons and neutrons. Very high melting and boiling points, insoluble in water and not good electrical conductors A table that classifies elements by their physical and chemical properties; rows are called periods; columns are called groups; Formed when one or more electrons are transferred from one metal to non-metal atom Very high melting and boiling points, soluble in water and good electrical conductors in solution or molten A chemical bond formed when non-metal atoms share electrons The number of protons in the nucleus of an atom Atoms of the same element that have different numbers of neutrons The smallest unit of matter that constitutes a chemical element. Heavy uncharged particles found within atomic nuclei The sum of the number of neutrons and protons in an atomic nucleus Heavy positively charged particles found within atomic nuclei. From low to high melting and boiling points, insoluble in water and very good electrical conductors
