A compound is a substance formed when two or more chemical elements are chemically bonded together. The atoms of the elements are held together by one of the various types of chemical bonds such as covalent bonds, ionic bonds, metallic bonds, etc.

Two types of compounds exist: molecular compounds and ionic compounds.

1. Molecular compounds are formed when elements share electrons in a covalent bond to reach octet state. They tend to be gases, liquids or low melting point solids, as they are held together by relatively weak force.

2. Ionic compounds are formed when one element donates an electron to another in an ionic bond, creating ions. These ions are then attracted to each other in a large, repeating lattice structure. Ionic compounds are generally solids with high melting points.

Examples of compounds include water (H2O), carbon dioxide (CO2), and sodium chloride (NaCl).
