Question

State two chemical properties which can be used distinguish a metal form a non metal​

Answer 1

Answer: The chemical property which can be used to distinguish between a metal and a nonmetal is the formation of positive ions by metals. Metals form positive ions whereas nonmetals form negative ions. As a result, oxides of metals are basic whereas the oxides of nonmetals are acidic in nature.

Answer 2

1. Metals are electropositive in nature whereas non-metals are electronegative in nature.
2. Metals form basic oxides except $Cr_{2} O_{3},$ $ZnO,$ $MgO$ whereas non-metals form acidic oxides except $CO,$ $NO_{2}, H_{2}O,$ (neutral oxides).
3. Metals form positive ions whereas non-metals form negative ions.
