J. Thomson 23 Jonh Dalton 24 Ionic crystals A grouping of electrons surrounding the nucleus of an atom Heavy positively charged particles found within atomic nuclei. Negatively charged particles, with very small mass, found outside the nucleus Very high melting and boiling points, insoluble in water and not good electrical conductors A chemical bond formed when non-metal atoms share electrons 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 Very high melting and boiling points, soluble in water and good electrical conductors in solution or molten Two or more non-metal atoms held together by covalent bonds The sum of the number of neutrons and protons in an atomic nucleus Formed when one or more electrons are transferred from one metal to non-metal atom 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. Heavy uncharged particles found within atomic nuclei Atoms of the same element that have different numbers of neutrons An attraction between a positive metal ion and the electrons surrounding it Charged atoms The smallest unit of matter that constitutes a chemical element. A table that classifies elements by their physical and chemical properties; rows are called periods; columns are called groups; The force that holds atoms together
