So now that we formed the three different hybrid orbitals, we are ready for these orbitals to interact with the one S orbitals of the H.
So we take three one S orbitals, we combine them with three SP two orbitals, and we form the following picture. So here we have our boron atom. The nucleus is in the middle here. It's not shown. We have one SP hybridized orbital pointing into the page into the board, and it's bonding to one of the S's. One is coming out of the board, and that is bonding to a second one S orbital.
