Question

Which of the following shows a correct Lewis dot structure

Answer 1

D is a correct Lewis Dot structure. Nitrogen has 4 valence electrons. 

Answer 2

The correct Lewis structure is D)

Step-by-step explanation:

The Lewis structure always has to represent the electrons of the most external level of the atom, also called valence electrons. These electrons will be involved in an eventual chemical reaction.

In this case the only correct answer is the structure of N which has 5 electrons on its most external level.
