Argon (Ar)
Sodium (Na)
Calcium (Ca)
Molecule
Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. Several methods of representing a molecule's structure.
Example :- H2O (water)
