neutron
a particle found in the neucleus of an atom. It is electrically neutral, carrying no charge
1 of 26
compound
the substance made when 2 or more elements are chemically bonded together

unsaturated hydrocarbon which contains a carbon-carbon double bond
24 of 26
fractional distilation
a way to separate liquids from a mixture of liquids by boiling the substances off at different temperatures, then condensing and collecting the liquids
