Explanation:

In periodic table:

Elements are arranged according to their atomic number in increasing order.
When we move left to right we move along a period.The period in the periodic table tell us about the principal quantum number,(n).
When move from top to bottom we are moving in group. The group in the periodic table tell us about the number of the valence electrons present in the valence shell of the elements of the particular group.

Answer:

A solution is a heterogeneous mixture

Explanation:

This statement that a solution is a heterogeneous mixture is completely and totally wrong.

A solution is a homogeneous mixture.

Homogeneous mixtures have their constituents existing in just one phase.

It is a homogeneous mixture of solutes and solvents.
In a solution, the solutes particles are distributed uniformly in the solvent.
The solute is the substance that is dissolved to make the solution.
Solutes are usually present in a small amount than the solvent.
The solvent acts as the dispersing medium which allows the solute to go into the solution.
The solute can be solid, liquid or gas.

The electron configuration of V³⁺ is [Ar] $3d^2$ . The ion is paramagnetic because it has two unpaired electrons

<h3>What is paramagnetic?</h3>

A weak magnetic field supplied externally can weakly attract some materials, which then create internal magnetic fields that are directed in the same direction as the applied magnetic field. This phenomenon is known as paramagnetic.
Diamagnetic materials, in contrast, are attracted to magnetic fields and produce induced magnetic fields that are directed in the opposite direction from the applied magnetic field.
The majority of chemical elements and some compounds are considered to be paramagnetic materials.
Paramagnetic materials have a relative magnetic permeability that is somewhat more than 1, which makes them attracted to magnetic fields.
The applied field induces a linearly decreasing magnetic moment that is relatively weak.
Modern experiments on paramagnetic materials are frequently done with a sensitive analytical balance since it typically requires a sensitive analytical balance to identify the effect.
