This is called a compound.
compound
A compound is a substance whose smallest unit is made up of more than one element and cannot be separated by physical means. Compounds are formed when atoms of different elements chemically bond together in specific ratios.
An element is a substance whose atoms all contain the same number of protons and the same number of electrons. The number of protons in an element's atom determines its atomic number and defines its chemical identity.
Compounds have atoms of more than one element.Covalent Compounds have covalent bonds between the atoms as in Water (H2O), or methane (CH4).Ionic Compounds have ionic bonds between the atoms such as Salt (NaCl) which will dissociate into ions in a suitable solvent such as water to give the ions Na+ and Cl-
Usual table salt requires two chemical elements to exists (Na+, Cl-).

Molecule.... and "whose" isn't a suitable pronoun referring to atomic particles
