Problem 27a

Given information

   ion is given. Orbital diagram must be written and then from the diagram it must be predicted whether the species is paramagnetic or diamagnetic.

Step-by-step explanation

Vanadium   has atomic number .

As per Aufbau's building up principle, electrons are filled in lower energy orbitals followed by higher energy orbitals.

According to Hund's rule while filling degenerate orbitals electrons occupy those orbitals singly and then pairing can takes place.

As per Pauli's exclusion principle no two electrons in an atom can have identical set of four quantum numbers.

Following these three basic rules electronic configuration is .

An ion is considered diamagnetic if there is no unpaired electron.  

An ion is considered paramagnetic if there is unpaired electron.
