Answer 1

Answer

Difference between metals and non metals are as follows :

Metals :

• They can easily expel an electron.
• They form ionic compounds
• Their oxides are having basic nature
• Their ionization enthalpies are low.
• Their electron affinity is less negative.
• Their electron negativily is less.
• Their reducing power is high.
• They cannot easily receive an electron.

Non - metals :

• They cannot easily expel an electron.
• They form covalent compounds
• Their oxides are having acidic nature
• Their ionization enthalpies are high.
• Their electron affinity is highly negative.
• Their electron negativily is more.
• Their reducing power is low.
• They can easily receive an electron.
