So it has six protons within the nucleus along with the six neutrons. And we have six electrons surrounding our nucleus. So two electrons will be in the one s orbital, two electrons will be in the two s orbital, and only two electrons will be in the two p orbital. So that means that there are four more electrons that can fit into our p orbitals because the p orbital can have a maximum of six electrons. So if we go up here, that means that we want, or carbon wants to gain four more electrons so that its electron configuration matches that of neon. So we basically want to attain this electron configuration.
