Compounds are molecules composed of different elements. For example,water (H2O), methane (CH4), carbon dioxide (CO2), ethanol (C2H6O) are considered compounds. However, molecular hydrogen (H2), molecular oxygen (O2), chlorine gas (Cl2), or molecular fluourine (F2) are not considered compounds as they are composed of a single element.
