### tetrahedral

can someone explain to me why tetrahedral is sp3 hybridization?

### Re: tetrahedral

Tetrahedral is an atom that has 4 bonds. This means that the 2s orbital and the 2p orbital hybridize to form sp3. To determine a molecule's hybridization, just count the number of bonds/lone pairs on the central atom (1 bond= s, 2 bond= sp, 3 bond= p2, 4 bond= sp3, 5 bond= sp3d, 6 bond= sp3d2, etc.)

### Re: tetrahedral

The type of hyrbrid orbital is named after the number of p orbitals that are needed for the central atom to have the right amount of bonds. An sp3 hybrid orbital is 1 s orbital and the three p orbitals of the same energy level (sp2 would be one s orbital and 2 p orbitals). because the central atom bonds with 4 other atoms in a tetrahedral arrangement, all four sp3 orbitals are needed to hold valence electrons.

The tetrahedral shape has 4 bonds, which in order 1, 2, 3, 4 bonds form s, sp, sp2 and sp3 hybridization.

### Re: tetrahedral

4 areas of electron density equals sp3 hybridization.

### Re: tetrahedral

Since there are four areas of electron density, it is sp3.
2=sp 3=sp2 4=sp3 5=sp3d 6=sp3d2
