Every compound is a molecule, but every molecule is not a compound. Why is this? Give an example with your answer. Plz help mehhh TvT

By definition, a molecule is a group of atoms bonded together. This means that it can be a mixture of two separate atoms (e.g. atom A and atom B bond together to make molecule AB). Molecules with two or more separate elements are called compounds.

Molecules can also be made of more than one atom of the same element (e.g. atom A bonds to another A atom to make molecule AA). This is not called a compound because they are not different elements.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
