O2 orbital model sp2 hybridization
Left: The different
microbeads required for modelling the oxygen molecule are shown together
with the beads, the plastic tubings for the pi bonds and the copper wire
for fixing the components.
Right: The bead model
of the oxygen molecule showing the sigma skeleton from the side:
Each of the two O atoms
(red beads) has 3 sp2 hybrid orbitals represented by one round
and two pear-shaped microbeads.
* The electron pair of the
sigma
bond is modelled by the golden and the white microbead,
* the four lone pairs of
electrons are modelled by the pear-shaped golden and white microbeads.
Each of the two O atoms
also has an unhybridized p orbital forming a pi
bond represented by the green-yellow plastic loop which is perpendicular
to the plane of the sigma skeleleton.
