And our electron, the single electron, will be found within this two p orbital. The same thing goes for the second methyl radical. We have SP two hybridized bond between the carbon and H, and we have one electron found within this two p orbital. Now, when these two methyl radicals begin to approach one another, the lobes, which are approximately two p, become approximately SP three hybridized. And that simply means that as they approach one another, these green sections become larger and larger, and these blue sections become smaller and smaller. And eventually, when they come close enough, there is an overlap between these two SP three hybridized orbitals, and they form what we know as a covalent bond.
