Metal oxides are chemical compounds containing a metal and oxygen; the are generally solids.
They are formed by reaction with oxygen from the air.
Oxides of more electropositive elements tend to be basic. They are called basic anhydrides; adding water, they may form basic hydroxides. For example, sodium oxide is basic; when hydrated, it forms sodium hydroxide.
Oxides of more electronegative elements tend to be acidic. They are called acid anhydrides; adding water, they form oxoacids. For example, dichlorine heptoxide is acid; perchloric acid is a more hydrated form.
Some oxides can act as both acid and base at different times. They are amphoteric. An example is aluminium oxide. Some oxides do not show behavior as either acid or base.
The oxides of the chemical elements in their highest oxidation state are predictable and the chemical formula can be derived from the number of valence electrons for that element. Even the chemical formula of O4, tetraoxygen, is predictable as a group 16 element. One exception is copper for which the highest oxidation state oxide is copper(II) oxide and not copper(I) oxide. Another exception is fluorine that does not exist as expected as F2O7 but as OF2.[1] Since F is more electronegative than O, OF2 does not represent an oxide of fluorine, but instead represents a fluoride of oxygen. Phosphorus pentoxide, the third exception is not properly represented by the chemical formula P2O5 but by P4O10.

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
Are metals oxides acidic?
No, metal oxides are basic in nature.
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 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.
Does Metal oxides have pH greater than or less than 7?
metal oxides are basic in nature.. so their pH is more than 7
Why metal oxide are amphoteric in nature?
according to acid base definations base is such thing which accept proton easily.in metal oxides ,metal has ability to give proton and oxygen has ability to accept it.both are strong conjugat acid and base.so the metal oxides are amphoteric in nature.
What are mettalic oxides in nature?
Mettalic oxides are basic in nature
Are metal's oxides gases or bases?
Metal oxides are typically basic.
Is sulfur dioxide gas basic or acidic in nature?
sulphur dioxide is an acidic gas. Remember;- Groups 1 & 2 oxides are basic. None metal oxides are acidic.
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.
What do metal oxides form?
Metal Salts + water
