Answer:
Molecules can be made of one type of element pr a mixture of element.
Molecule is two or more atoms bonded together.
Compound act like a different substance (because have different properties from its constituent elements).
Explanation:
A molecule is the combination of one or more atoms. These atoms may be from different elements are of the same elements. All the compounds are molecule but not all the molecules are compound. For example,
H₂O is a water molecule and also a compound. H₂ is just a molecule not a compound because both atoms are from same element.
The compound have different properties from its constituent elements. e.g water is compound made up of hydrogen and oxygen. Hydrogen is flammable gas and oxygen support combustion, while water doesn't have these properties. However in mixture elements retain their own properties that's why mixture is different from the compound.
