Answer:
(6 dots) Br (one line) N (one line) Br (6 dots)
(one line)
Br (6 dots)
Explanation:
Add valence electrons
5+3(7) = 26
Subtract 26 - 24 = 2 (next multiple of 8)
This tells us the number electrons on central N atom.
Next, know that N like 3 bonds, while Br likes 1 bond. (hence 1 line)
Now, Br wants 8 electrons, so add 6 dots.
Note: one line are bond is equal to 2 electrons.
