An ion is an atom or molecule that has a net electrical charge. 21 of 26 what is molecule ? a group of atoms bonded together, 22 of 26 what is condense ? vapour to a liquid. 23 of 26 what is solidify mean ? r become hard or solid. 24 of 26 what is a mixture ? can be separated by physical processes (no chemical changes are involved). 25 of 26 what is RAM? The average mass of a single atom of an element relative to carbon 26 of 26
