So the carbon has the following electron configuration. It has a total of six electrons. Two electrons go to the one S, two electrons go to the two S and two electrons still to two P. Now, each H atom has one electron each. And that means that electron goes into the one x orbital. So we have one balance electron per H atom and four balance electrons two plus two four for the carbon atom. Now, before the carbon can combine with the H atoms to form our methane, hybridization must take place.
