A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).

Key Points

• Molecules are neutral and do not carry any charge.
• A molecule may consist of nonmetallic atoms of a single chemical element, as with oxygen (O2), or of different elements, as with water (H2O).
• The geometry and composition of a molecule will determine its chemical and physical properties.
• Isomers are molecules with the same atoms in different geometric arrangements.

Terms

• moleculeTwo or more atoms that are held together by a chemical covalent bond.
• compoundwhen two or more different atoms are held together by a covalent bond. All compounds are molecules but not all molecules are compounds.
• covalentwhen 2 or more nonmetallic atoms are bound together by sharing electrons.
• isomerMolecules with the same number of atoms in different geometric arrangements
