Answer:
Metals Non-metals
Metals are electro-positive. Non-metals are electronegative.
Metals reacts with oxygen to form basic oxides.
4Na+O

O
Non-metals react with oxygen to form neutral or acidic oxide.
C+O

Metal oxides and hydroxides bonds have ionic bonds. Non-metal oxides and hydroxides have covalent bonds.
Metals react with water to form hydroxide and hydrogen.
2Na+2H

O→2NaOH+H

Non-metals do not react with water.
Metals react with dilute acids to form salt and H

. Non-metals do not react with dilute acid and they can not displace hydrogen.
Metals react as reducing agent by donating electrons.
Na→Na
