Question

Electron dot structure for NBr↓3

Answer 1

(6 dots) Br (one line) N (one line) Br (6 dots)

(one line)

Br (6 dots)

Step-by-step 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.
