Covalent compunds consist of moleculs whose atoms are
held togethre by covalent bonds. For example, an ammonia molecule is made up
three hydrogen atoms and one nitrogen atom. Each covalent bond consist of two
shared electrons one from the nitrogen atom and one from a hydrogen atom.

| Early concepts in covalent bonding arose from this kind of i mage of the molecule of methane. Covalent bonding is implied in the Lewis structure that indicates sharing of electrons between atoms. |
