Question

what is the chemical properties of metals and nonmetals

Answer 1

Chemical Property of Metals:

Usually have 1-3 electrons in their outer shell.

Lose their valence electrons easily.

Form oxides that are basic.

Are good reducing agents.

Have lower electronegative.

Chemical Property of Non Metals: 

Usually have 4-8 electrons in their outer shell.

Gain or share valence electrons easily.

Form oxides that are acidic.

Are good oxidizing agents.

Have higher electronegative.
