H2O is a Compound & Molecule.

Here's why:

1. Compound: A compound is a substance formed when two or more chemical elements are chemically bonded together. In H2O, the Hydrogen (H) and Oxygen (O) elements are chemically bonded together, hence it is a compound.

2. Molecule: A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of hydrogen and oxygen in a molecule of water are held together by chemical bonds, hence H2O is also a molecule.
