And this is known as the bonding molecular orbital. So let's look at the Creation of the Antibinding molecular orbital. Now, what this means is that we're combining two orbitals where one of the orbitals one of the one s orbital is of a positive sign and the other atomic orbital, the other one s atomic orbital is of a negative sign. And remember, orbitals are wave functions. And that simply means that when our orbitals go from a positive sign to a negative sign, they must go through the .0. And this is known as the Nodal plane.
