Question

Differenciate between metal and non metal on the basis of physical and chemical properties in tabular form

Answer 1

Metals are dense, shiny, good conductors of heat and electricity, and easily lose electrons in chemical reactions. Nonmetals are not dense, dull, do not conduct heat and electricity, and tend to gain electrons. Metalloids are elements that have properties of both metals and nonmetals.

Answer 2

Metals

1. Oxides of metal are basic in nature.
2. Metals displace hydrogen from dilute acids.
3. Metals form chlorides which are electrovalent or ionic compounds
4. They displace hydrogen from water



Non-Metals



1. Oxides of non-metals are acidic in nature.
2. They cannot do so
3. Non-metals form chlorides which are covalent compounds.
4. They cannot do so
