O molecule has sp3 hybridization, and the bond angle of H-O-H is 104.5. Define covalent bonding. This theory basically says that bonding and non-bonding electron pairs of the central atom in a molecule will repel (push away from) each other in three dimensional space and this gives the molecules their shape. It is a solid at room temperate. The molecular geometry of any molecule depends on its Lewis structure, the arrangement of atoms, and its electrons. The mixing and overlapping are occurring among the atomic orbital of similar energy. The VSEPR theory states that, because of their mutual repulsions, valence electron pairs surrounding an atom stay as far as possible from one another. 2. It makes a single hydrogen atom to have one valence electron. 0
