Simply because it is a compound of a metal and oxygen. All elements want to have their most outter electron shell completely filled, so they share electrons with other elements or even the same element, to achieve this goal. In your situation, it is metal and oxygen like iron III and Oxygen (Fe2O3).

What are minerals made out of oxygen and metal called?
oxides
What are metal oxides with examples?
Metal oxides are oxides of metal. They are ionic in nature and form basic oxides. Eg: Na2O, MgO,etc
Is metal oxide is a base?
Yes, certain metal oxides, mostly from the middle groups of the transition metals are acidic. Chromium and rhenium, for example, both form oxides which are acidic in water.
Are metal's oxides gases or bases?
Metal oxides are typically basic.
Are metal oxides neutral?
Many metal oxides are alkaline and form hydroxides in the presence of water.
Are all oxides acidic?
No. A number of metal oxides are basic.
Are metals oxides acidic?
No, metal oxides are basic in nature.
Why are aluminium and zinc oxides called amphoteric oxides?
These oxides are called amphoteric because they can dissolve in acidic solutions to form metal cations in the solutions but can also dissolve in strongly alkaline aqueous solution to form oxyanions of the metals: aluminate or zincate.
What is oxide ores?
Those ores which contain metal in the form of oxides are called as oxide ores.
How does the acid-base nature of the oxides in the period 3 change with the increasing atomic number?
basic metal oxides change to acidic non-metal oxides
Is it true that non metal oxides which react with water to form acids are called acidic oxides?
non metal oxides react with water to give oxyacid but also do undergo disproponation depending on the oxidation number ( oxidation number is increased and decreased, respectively) of the metal N2O5 + H2O → 2HNO3 3NO2 + H2O → 2HNO3 + NO
What do metal oxides form?
Metal Salts + water
