What is hybridation?

It's when whole nation goes to hybrid cars... :D... jk......

Hybridization is when electrons become exicted and change into a mix of orbitals, which is then called like an sp orbital. These are then able to link with other atoms. so if the element had an extra of 2 electrons like Calcium, whne the electrons were excited they would now move into the sp orbitals and be able to connect to other elements.
