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