Now, when this S combines with this positive P, we get the following hybridized orbitals. In other words, this positive region simply combines with this positive region, and this becomes smaller. So a positive S orbital combines with a positive p orbital. The two greens combine, the blue becomes smaller to form an enlarged positive green lobe and a smaller or thinner negative blue lobe. And the same happens when this part is negative. We get the following because two negative lobes combine to form this enlarged negative section, enlarged negative lobe, and the smaller positive green lobe.
