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