a)
Interpretation:
The element for given electron configuration has to be identified.
Concept Introduction:
Electronic configuration: The electronic configuration is the distribution of electrons of an given molecule or respective atoms in atomic or molecular orbitals.
The important there rules for electronic configuration given below:
Aufbau principle: This rule statues that ground state of an atom or ions electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. If consider the 1s shell is filled the 2s subshell is occupied.
Hund's Rule: The 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.
Pauli exclusion rule: an atomic orbital may describe at most two electrons, each with opposite spin direction.
Paramagnetic: The Paramagnetic properties are due to the presence of some unpaired electrons, and from the realignment of the electron paths caused by the external magnetic field.
Diamagnetic properties: In diamagnetic materials all the electron are paired so there is no permanent net magnetic moment per atom.
b)
Interpretation:
Whether the given element obeys magnetic property has to be predicted.

Interpretation:
The number of unpaired electrons in (III) oxidation state of Cobalt has to be predicted.
