== Introduction ==
'''Magnesium oxide''' is an ionic compound that appears as a white, powdery [[solid]]. It can also be referred to as magnesia. This compound is perhaps best known for its use as a medication that can treat symptoms such as heartburn or indigestion. It can be formed by burning magnesium ribbon in the air and also occurs naturally as periclase. Magnesium oxide is a relatively safe chemical, but it can be a mild irritant.
