In a Lewis structure involving bromine and chlorine, if a central bromine atom has two lone pairs, how many chlorine atoms must be present?
3 Cl atoms
If there are two lone pairs, that means four of bromine's seven valence electrons are occupied. That leaves three available for covalent bonds to three chlorine atoms.

Two lone pairs indicate that four of the seven valence electrons of bromine are occupied. Three are now free to form covalent bonds with the remaining three chlorine atoms.

Why are Lewis structures important ?

We must also learn about the bond angle in order to recognize and fully describe the three-dimensional form of a molecule. Lewis Lewis Dot Structures are essential for identifying the valence electrons and are used to determine the geometry of molecules.

What does the Lewis structure's three lines stand for?

A line or two spots between the linked atoms signify a bond, that is made up of two shared electrons. The symbols for double and triple bonds, respectively, are three and two lines/(pairs of electrons).
