Based on the trend in valence electrons across periods for main-group elements, how many valence electrons does nitrogen (N) have?
A. 2.
B. 5
C. 1
O O
D. 6

5

Explanation:

I know because I answer this question before and it was right

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

we need the questions , i may then you.
