Molecule A molecule is a group of atoms that are chemically bonded together (held together by attractive forces). A molecule can be defined as the smallest particle of an element (e.g., O2) or a compound (e.g., H2O) that is capable of independent existence and shows all the properties of that substance. Atoms of the same element (e.g., O2) or of different elements … [Read more...]
Elements, Metalloids, Compound, Mixtures vs. Compounds
