For a straightforward answer: use this formula: Bond order = [(Number of electrons in bonding molecules) - (Number of electrons in antibonding molecules)]/2. Now, if we see the electronic configuration of carbon in its ground state it will be represented as 1s 2 2s 2 2p 2. Each of the two sp hybrid orbitals holds one electron and is thus half filled and available for bonding via overlap with a Cl 3p orbital.

Write orbital diagram for Cd2+ ? When atomic orbitals hybridize, the valence electrons occupy the newly created orbitals. B) An orbital that penetrates into the region occupied by core electrons is more shielded from nuclear charge than an orbital that does not penetrate and therefore has a lower energy. Clicker 8. It can be excited to either the d z 2 or the d x 2-y 2 orbital: d xy--> d z 2 (higher energy) d xy--> d x 2-y 2 (lower energy) The first transition is at higher energy (shorter wavelength) because in the excited state the configuration is (d yz 1 d xz 1 d z 2 1). However, we will take first take both carbon and hydrogen molecule separately and draw their orbital diagrams. (Treat HHe as a diatomic molecule with three electrons.) Since the s sublevel consists of just one orbital, the second electron simply pairs up with the first electron as in helium. Answer Save. Exceptions include calcium sulfate, strontium sulfate, lead(II) sulfate, and barium sulfate, which are poorly soluble. 5 years ago. If we build the MO diagram for "N"_2, it looks like this: First though, notice that the p orbitals are supposed to be degenerate.
