Deionized water is water that has been passed through resins that remove electrically charged material from the water. If it has not come into contact with carbon dioxide, the pH of deionized water is 7. Its pH is approx... More »

In chemistry, ionic bonds and covalent bonds are both methods atoms use to combine into larger molecules by swapping or sharing outer electrons. An atom's energy level is determined by the number and configuration of ele... More »

A monoatomic gas is a gaseous substance composed of molecules that each contain only one atom each rather than molecules formed by the bonding of two or more atoms. Examples of monoatomic gases are helium, argon and neon... More »
