So one goes into here, one goes into here, one in here and one in here. Now, the carbon, which has undergone hybridization, is ready to interact with four other one s orbitals. So here we take the four one s orbitals. We place each on to the positive green lobe, and we get our methane molecule. So a simpler way of looking at it is via this black diagram. So here we have our carbon nucleus.
