Answer:
The coordination number is 4.
Explanation:
- Square planar clusters can be either cis or trans, as they form 180 and 90-degree bond angles. Therefore, a pair of ions may be adjacent (cis) to one another and immediately across (trans) from one another.
- A square planar molecule could never be simultaneously cis and trans, so because several coordinators are 4.
- Since linear complexes have only an angle of a bond of 180 degrees, they can not have cis or trans-isomers. In the coordination complex, there is only yet another way possible of bonding the two binding sites to the steel.
The closer the orbitals are to the nucleus, the lower they are in energy.
Atomic orbitals are filled with electrons the energy goes from lowest to highest
When multiple orbitals of equal energy have only one electron, the electrons in each must all have the same spin. However, the orbital diagram violates Hunds Rule.
Pauli's exclusion principle states that in an atom or molecule, no two electrons can have the same four quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
Hund's rule of maximum multiplicity states that every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
