Well, this is simply an orbital produced using 50% S orbitals and 50% P orbitals. In other words, when we're combining our orbitals within that given atom, 50% comes from S and 50% comes from P. And this is known as an SP hyper dice orbital. That's exactly what we have in this situation here. So let's look at an example in nature. So where is this evidence? So let's look at one particular example in which a Beryllium atom combines with two H atoms.
