The electron configuration of V³⁺ is [Ar]
. 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.

Answer:
the systematic name is called Lithium sulfide.
6 electrons in total
2 on the first shell
4 on the second shell
Second Ionization energy is required to move from Ca⁺ to Ca²⁺ + e⁻. Hence, option D is correct.
<h3>What is first ionization energy?</h3>
First ionization energy: The energy needed to remove the outermost, or highest energy, an electron from a neutral atom in the gas phase.
An element's second ionization energy is the energy required to remove the outermost, or least bound, an electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first.
Let us write the reaction equation properly:
Ca⁺ → Ca²⁺ + e⁻
In the reaction above, we see that calcium goes from a single charge to being doubly charged by losing an electron.
Different atoms bind their valence electrons with different amounts of energy. We must supply enough energy to remove the most loosely held electrons in an atom. This amount of energy required is called ionization energy.
The first ionization energy removes the outermost electron and makes the atom to become an ion.
Hence, option D is correct.
