Dear Student,

Please find below the solution for your asked query:

Metallic oxides are chemical compounds of metals with oxygen
like Na2O, MgO, K2O, CaO, etc
Metallic oxides are basic in nature because they react with
dilute acids to form salt and water
They also react with water to form metal hydroxides which are
alkaline in nature, as these metal hydroxides release OH- ions in
solution
Example - CaO + H2O →
Ca(OH)2
