I have been learning about SP3 hybridisation and slightly confused why it it results in 4 sp3 orbitals.
My understanding is this...
The S orbital is spherical and uniform whilst the p orbitals are made of 2 lobes.
There are 3 p orbitals Px Py and Pz.
So if each of these p orbitals combines respectively with the s orbital you end up with 3 new ones. Where does the remaining orbital come from?
Thanks very much,
