Ten plants (five in Kansas, four in What is Helium?. The atomic number of helium is 2, meaning each atom of helium has two protons.. Helium has the lowest melting point and boiling point of the elements, so it only exists as a gas except under extreme conditions.. A substance that speeds up a reaction without being consumed itself. How? By providing a new pathway for the reaction, one with a lower activation energy. Catalyzed Reaction.

Definition. :. A catalyst is define as a substance which alters the rate of a chemical reaction, itself remaining chemically unchanged at the end of the reaction. This phenomenon is called catalysis..
