So two two and two gives us six. So this is in fact, a correct picture. Now this is once again a sigma bond, and this is our non bonding pair of electrons. So let's go to part C.
In part C we have NH three or ammonia. So in this case, we have an N atom. So let's throw out our electron configuration for N.
So two electrons go into the one s, two electrons going to the two s, and now we have three electrons going to our two p. So altogether we have five balanced electrons because we have five electrons in the outermost shell for anna.
