. What type of oxides are formed by metals

Best Answer


 The nature of oxides of many  metals is basic . Metals can form  simple oxide, peroxide (Na2O2) or superoxide (K2O) 

Some metals oxides can react with both acid and base are called amphoteric oxides.

Example- lead oxide( PbO) , Aluminum oxide(Al2O3 ).

When we move from left to right in  the period the tendency to form basic oxide decreases as polarizing power of cation increases.

Final Answer:-

 Metals form basic as well as amphoteric  oxide.
