Four sp three hybrid orbitals are formed on carbon.
Think of a carbon atom like a toy with four empty pockets that want to hold hands with other atoms, and hybridization is how those pockets rearrange to be evenly spaced. When carbon becomes sp three hybridized, one s pocket and three p pockets mix together to make four identical sp three pockets that point toward the corners of a tetrahedron so they stay as far apart as possible. This mixing gives each new pocket the same shape and energy, which helps carbon form four single bonds that are stable and spread out in three dimensions. If you picture a pyramid with a triangular base, the carbon sits in the middle and the four pockets reach out to the corners.
Students often think sp three means there are three of something instead of four, so remember the number after the letter shows how many p orbitals mixed with the s orbital, not how many final orbitals you get, and the result is four identical orbitals. Some believe hybridization changes the total number of electrons, but hybridization only redistributes the same electrons into new shaped orbitals, so do not try to add or remove electrons when drawing hybrids. Others draw the orbitals lying flat or clustered instead of pointing to the corners of a tetrahedron, so always draw them spaced evenly for correct shape.
