An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2- atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2.
Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
alkali metal + oxygen --> metal oxide metal oxide + water--> metal hydroxide metal hydroxides are strong alkalis, corrosive pH=14
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
Magnesium oxide will react with water to form Magnesium Hydroxide. Magnesium Hydroxide will not reat further with water

Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
metal hydroxide
Metal oxide + Water --> Metal hydroxide
The Metal hydroxides are strong base, therefore metal hydroxide decomposes on heating to form metal oxide and water.
A basic solution
synthesis
acid+ metal oxide --> salt + water
Metal carbonate Metal oxide Metal hydroxide
No potassium OXIDE is not: IT IS A METAL. IT IS A METAL.And it is not a NONmetal either.Potassium OXIDE K2O is a basic oxide: with water it forms (only) potassium hydroxide, KOHPotassium (elemental) is a alkali metal
synthesis
The easiest way of remembering whether something is a base is by remembering: "A base is a metal oxide, metal hydroxide, or ammonia." Sodium Hydroxide comes under the metal hydroxide category, so yes, it is a base.
