Question

differentiate between molecule of compound and molecule of element in tabular form?

Answer 1

answer
is
Firstly,
Molecule:
The combination of different atoms is called molecule, The atoms may be of any type.
Examples of Molecules:

Hydrogen gas molecule = H₂
Nitrogen gas = N₂
Carbon Dioxide gas = CO₂
Water = H₂O
Calcium Oxide = CaO

H₂ and CO₂ and H₂O are all molecules. But, all these molecules are not compounds.
Compound:
The molecules formed by the combination of different types of atoms is known as compound.
Examples of Compounds:

Carbon Dioxide gas = CO₂
Water = H₂O
Calcium Oxide = CaO

These are smallest constituent unit of substance and the whole substance is referred as compound.
Explanation:
Atoms are combined chemically to form molecules. The substance containing same kind of atoms is known as elements.
Similarly, The substance containing same type of molecules is known as compound.

In another way, the smallest constituent unit of element is atom and smallest unit of compound is molecule.

Note: By smallest unit, we mean a specie which posses the properties of that substance.
