Construct the orbital diagram for Ni.
♦ Relevant knowledge
The orbital diagram is the best probability of where electrons can be found within the nucleus of an atom. The orbital diagram explains the way that atomic orbital combine, and the molecule that is formed within a the molecule. There are also orbitals in the atom that overlap with one another.

This problem was solved using orbital diagrams.
Orbital diagrams show the total number of electrons within an atom.
The following rules are helpful in creating the orbital diagram:
Pauli explosionprinciple states that only two electrons can fit in a single orbital.
Aufbau principle states that each electron occupies the lowest-energy orbital first.
Hund’s rule states that each orbital must be singly occupied by one electron before it can be double occupied. The spin of all electrons in an orbital singly occupied is the same.
Nickel’s atomic number is 28. There are therefore 28 electrons in a nickel atom.
Start by filling the orbitals with electrons of lowest energy. Each orbital can only be occupied with one electron. Only two electrons can be inserted into an orbital with the opposite spin. The orbital diagram for nickel can be found below.
