Magnetic moment; of TI, V, Cr, Mn.
Solution and Explanation
Titanium (Ti): In its elemental form, titanium is paramagnetic, meaning it has a weak attraction to a magnetic field. The magnetic moment of titanium is approximately 0.01 Bohr magnetons (BM). However, the magnetic properties of titanium can be influenced by impurities or alloying with other elements.
Vanadium (V): Vanadium is also paramagnetic, and its magnetic moment is around 0.02 BM. Similar to titanium, the magnetic properties of vanadium can vary based on its alloying or impurity content.
Chromium (Cr): Chromium is known to exhibit antiferromagnetic behavior in its pure form. In an antiferromagnetic material, neighboring atoms have opposing magnetic moments, resulting in a net magnetic moment of zero. However, under certain conditions, chromium can display weak ferromagnetic properties. The average magnetic moment of pure chromium is approximately 0.06 BM.
Manganese (Mn): Manganese has diverse magnetic properties depending on its chemical environment. In its pure form, manganese is paramagnetic, with a magnetic moment of around 5.0 BM. However, manganese can form compounds with various oxidation states, and its magnetic moment can significantly vary depending on these states. For example, Mn2+ ions can exhibit a magnetic moment of about 5.9 BM, while Mn3+ ions have a magnetic moment of approximately 4.9 BM.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
