Answer

The lewis structure is shown in the picture.

Work Step by Step

1) Draw the N connected to each other and then connect one H to each N. 2) Count the number of valence electrons involved in the bonding, which is 6. There should be 5+5+1+1 =12e. So make one more bond. 3) Now there are 8 e. 4) Since N has already made three bonds and H has made one bond. Place the remaining electrons as lone pairs on both the N's. 4) Now count the valence electrons, it should be 12e.
