JimBob says water is NOT a compound. He says only hydrogen is used to make water. What is wrong with this?

• Water is a compound because it is made of hydrogen which is made of 2 types of atoms.

• Water is a compound because compounds are only made up of 1 type of element.

• Water is a compound because compounds must contain two or more elements, and oxygen is also combined with hydrogen to make water.
