Very high melting and boiling points, soluble in water and good electrical conductors in solution or molten An attraction between a positive metal ion and the electrons surrounding it Two or more non-metal atoms held together by covalent bonds A grouping of electrons surrounding the nucleus of an atom Heavy positively charged particles found within atomic nuclei. The number of protons in the nucleus of an atom Liquids or gases at room temperature. Some can be solid, but they melt at low temperatures. Atoms of the same element that have different numbers of neutrons Heavy uncharged particles found within atomic nuclei The sum of the number of neutrons and protons in an atomic nucleus Charged atoms A table that classifies elements by their physical and chemical properties; rows are called periods; columns are called groups; The smallest unit of matter that constitutes a chemical element. A chemical bond formed when non-metal atoms share electrons From low to high melting and boiling points, insoluble in water and very good electrical conductors Formed when one or more electrons are transferred from one metal to non-metal atom
