Learn Lewis dot structure and lone pair.
What is lewis structure?
The valence shell electrons of a molecule are depicted in a highly condensed manner in a Lewis structure. It serves as a visual representation of the electron arrangements around specific atoms in molecules. Electrons are represented as "dots" or "lines" when two atoms are bonded together.
What is lone pair?
Valence electron pairs known as lone pairs are those that are exclusive to one atom. They are not involved in the synthesis of covalent bonds. An example is the two lone pairs on the oxygen atom in the water molecule. Another illustration is the lone pair on the nitrogen atom of the ammonia molecule.
Four of the seven valence electrons in bromine are occupied if there are two lone pairs. Thus, three chlorine atoms can form covalent connections with the remaining three.
Therefore, three chlorine atoms can form covalent connections with the remaining three.
