Explain the chemical properties of metals and non metals on the basis of reaction with oxygen and water
Answers
Answer:
this is your answer
Explanation:
Metals react with oxygen to form basic oxides. Zn and Al form amphoteric oxides which show the properties of both acidic and basic oxides. Mostly, metal oxides are insoluble in water. ... Non-metals react with oxygen to form oxides.
Answer:
Metals Non-metals
Metals are electro-positive. Non-metals are electronegative.

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.

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.
