Interpretation:
The physical properties that distinguish between metals and non-metals need to be explained.
Concept introduction:
The periodic table is a proper arrangement of the elements according to their increasing

Answer to Problem 33A
The physical properties on the basis of which metals and non-metals can be distinguished are density, ductile nature, conductor of heat and electricity.
Explanation of Solution
The difference based on physical properties −
Properties | Metals | Non-metals |
Density | Metals are present with high density. | Non-metals are found with low density. |
Ductile nature | Metals are soft, tensile, and ductile. | They are hard and brittle. |
Conductor of electricity | Metals are used as good conductors of electricity. | They are poor conductors of electricity. |
Conductor of heat | Metals are good conductors of heat. | Non-metals are poor conductors of heat. |
Thus, the physical properties as density, tensile nature, and conductors for heat and electricity can help to differentiate between metals and non-metals.
