What are Metal Oxides
Metal oxides are chemical compounds containing a metal and one or more oxygen atoms. Here, the oxidation number of oxygen is -2, and it is essentially the anion where metal is the cation. Alkali metals (group 1 elements), alkaline earth metals (group 2 elements) and transition metals (some d block elements) form ionic oxides. But metals showing high oxidation states can from oxides with a covalent nature.
Metal oxides are crystalline solid compounds. These compounds contain a metal cation and an oxide anion. These compounds are often basic compounds and can react with water giving a base. If not, they can react with acids forming a salt of the metal.
There are three types of metal oxides formed alkali metals and alkaline earth metals.
Oxides containing oxide anions (O2-)
Peroxides containing peroxide anions (O–)
Superoxides containing superoxide anions. (O2–)
The number of oxygen atoms that bind with the metal ion depends on the oxidation number of the metal ion. Alkali metals form only monovalent cations. Therefore, they form only M2O type oxides (where M is the metal ion and O is oxide anion). Alkaline earth metals form divalent cations. Therefore, they form MO type cations.
What are Non Metal Oxides
Nonmetal oxides are oxide compounds formed by nonmetal elements. Most p block elements are nonmetals. They form various oxide compounds. Nonmetal oxides are covalent compounds since they share electrons with oxygen atoms to form oxide molecules.
Most nonmetal oxides give acids after reacting with water. Therefore, nonmetal oxides are acidic compounds. For example, when SO3 is dissolved in water, it gives H2SO4 solution, which is highly acidic. Nonmetal oxides react with bases to form salts.
Nonmetal oxides can form oxyacids. Oxyacids yield hydronium ions in aqueous solutions. There are two types of acidic oxides:
Acid anhydrides whose nonmetal exhibits one of its most common oxidation state such as in N2O5, SO3.
Acid oxides whose nonmetal does not exhibit its most common oxidation states. Ex: NO2, ClO2.
