An atom's dense central core, containing protons and neutrons. Negatively charged particles, with very small mass, found outside the nucleus Formed when one or more electrons are transferred from one metal to non-metal atom The smallest unit of matter that constitutes a chemical element. The number of protons in the nucleus of an atom A chemical bond formed when non-metal atoms share electrons 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 An attraction between a positive metal ion and the electrons surrounding it Very high melting and boiling points, soluble in water and good electrical conductors in solution or molten The sum of the number of neutrons and protons in an atomic nucleus 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.
