Electrolysis: The passage of a strong electric current through a molten ionic compound sometimes can decompose the compound into its elements.
Electron: A negatively charged particle that surrounds the atom.
Electron Shell: The atom's "boundary." The shell facilitates the electrons that move around in it.
Element: A substance composed of atoms with identical atomic numbers.
Evaporation: The process by which a liquid turns into a gas. This only takes place at the surface of liquids, as opposed to boiling that takes place throughout the liquid.
Filtration:
A separating process in which a mixture of liquid and solid is separated by
trapping one of the states, usually the solid using filter paper, for
example.
Formality: The number of formula weights of solute per liter of solution.
Ion: A particle obtained by adding or removing electrons from atoms or molecules.
