Oxygen has 2, for you, when 1 s orbital unites with 2 p orbitals it. . It can be studied with the help of the Valence Bond Theory (VBT) which says that atomic orbitals mix and intermix to produce new hybrid orbitals that can pair valence electrons to form new chemical bonds. for C in CSe2? Thinking about the other 2 electrons of 3p which were not associated with hybridization? My aim is to uncover unknown scientific facts and sharing my findings with everyone who has an interest in Science.
