So we have a net of eight electrons. And that concludes our picture for b. Let's jump to part C. In part C, we have this ammonium atom, or NH, four positive. That means nitrogen has one less electron than it does in its neutral state. So let's draw our electron configuration. For n.
One or two electrons go into the two s, two electrons go to the two or two electrons going to the one s, two electrons go to the two s, and two electrons go into the two p now, normally, in a neutral atom, we would have three electrons going to the two P. But because it has a plus one, that means it has one more proton in an electron.
