Using electron bookkeeping draw a Lewis dot diagram for NF2H and N2H2 determine how many electrons each atom should be assigned.

Thanks Guys I really appreciate it, my assignment is due tonight and the test is tomorrow, could you explain it,thanks

These are almost impossible to draw on this board. You have 26 electrons.
Draw N on a sheet of paper, place F, F, and H on each of three sides. Place two electrons between each to show the covalent bond. Place six more electrons around each F and place the last two electrons on the fourth side of N so it will be an unshared pair.

H:N::N:H with a lone pair above each N.

You post sounds as if you want the formal charge. The formal charge on all of the atoms in each structure is zero.

DR Bob this is what I drew, I know its not lined up but could you explain the method of electron booking for me.
Thanks again
