J. Thomson 23 Chemical bond 24 Mass number (A) Heavy positively charged particles found within atomic nuclei. A table that classifies elements by their physical and chemical properties; rows are called periods; columns are called groups; 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 Heavy uncharged particles found within atomic nuclei Very high melting and boiling points, soluble in water and good electrical conductors in solution or molten The smallest unit of matter that constitutes a chemical element. Charged atoms 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 Negatively charged particles, with very small mass, found outside the nucleus The sum of the number of neutrons and protons in an atomic nucleus A grouping of electrons surrounding the nucleus of an atom The force that holds atoms together A chemical bond formed when non-metal atoms share electrons Liquids or gases at room temperature. Some can be solid, but they melt at low temperatures. An atom's dense central core, containing protons and neutrons. Two or more non-metal atoms held together by covalent bonds The number of protons in the nucleus of an atom From low to high melting and boiling points, insoluble in water and very good electrical conductors
