There are 8 electrons involved in the structure.
Work Step by Step
1) Count the number of valence electrons in the structure. There are 8 electrons in total. (N=5 +H*3= 3). 2) Put N in between and H around it. Draw single bonds between the H and N. 3) Subtract the electrons involved in the bonds from the total number of electrons. (So 8-6=2). 4) Put the remaining electrons around the nitrogen.
