Question

which of the following represents the lewis symbol for nitrogen?

Explanation:

Nitrogen has 5 valence electrons. In a Lewis - symbol, the symbol of the element (N) is written, and dots are placed around it to represent the valence electrons. One pair of dots and three single dots are used to represent the 5 valence electrons of nitrogen.

Answer:

The Lewis - symbol with one pair of dots above the N and three single dots around the N (one on the left, one on the right, and one below) is the correct one. Without specific letter - labeled options, it's hard to give an exact choice from the provided images, but look for the one with 5 dots (a pair and three singles) around the N.
