The number of electrons surrounding the central atom of BBr 3 has to be given. Concept Introduction: Lewis structures are diagrams that represent the chemical bonding of covalently bonded molecules and coordination compounds. It is also known as Lewis dot structures which represents the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. The Lewis structure is based on the concept of the octet rule so that the electrons shared in each atom should have eight electrons in its outer shell. Atoms can be stable even though the number of valence electrons in the atoms in a molecule is less than eight and is called incomplete octet Atoms can be stable even though the number of valence electrons in the atoms in a molecule is more than eight and is called expanded octet
