Silicon - University of Denver
2002/11/30· Silicon, likewise, will not let go of its four valence electrons, and does not even like to share them very much if the alternative of sharing them with an oxygen atom is possible. Both carbon and silicon find that hybrid sp 3 tetrahedral orbitals are the most stable, with the angle between bonds equal to 109° 28'', the tetrahedral angle .
