Answer:
E) two or more atoms chemically joined together.
Explanation:
A molecule is known as the smallest particle of a large compound that is formed by the bonding of two or more atoms. The bonding between the atoms changes the physical and chemical properties of the particles.
The molecules are formed between atoms by either by sharing of the electrons called covalent bonds or the exchange of electrons called noncovalent bonds.
Thus, Option-E is the correct answer.
