Using orbital box diagrams and noble gas notation, depict the electron configurations of (a) V, (b) V2+, and (c) V5+. Is the element or any of the ions paramagnetic?

(a)

Interpretation Introduction

Interpretation:

The electronic configurations and paramagnetic, diamagnetic properties have to be identified for given the transitions metals of vanadium element.

Concept Introduction:

Electronic configuration: The electronic configuration is the distribution of electrons (e-) of an given molecule or respective atoms in atomic or molecular orbitals.

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.

Explanation

The Vanadium (V) has five electrons in the (4s) orbitals and (3s) electrons in 3d orbitals, the electrons filling method presented below.
