What are molecules meaning?
Molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.

What is molecules Class 9 notes?
Molecule. It is the smallest particle of an element or a compound which can exist independently. Molecules of an element constitute the same type of atoms. Molecules may be monoatomic, diatomic or polyatomic. Molecules of compounds join together in definite proportions and constitute a different type of atoms.

What is the difference between a compound and a molecule?
The molecule is when two or more than two atoms are bonded tighter together with a chemical force, whereas a compound is when two or more molecules are bonded tighter together with a chemical force. Every compound is made up of molecules. Therefore, every compound is a molecule, but it is not with the molecule.
