Key Insights

• 🤘 Transition metals have a magnetic moment, which is primarily due to the spin motion of the electrons.
• 🫚 The effective magnetic moment is calculated using the formula square root of (n + 2) Bohr magneton, where n represents the number of unpaired electrons.
• #️⃣ The number of unpaired electrons can be determined by analyzing the electron configuration.
• 😑 The effective magnetic moment can be used to determine the paramagnetic or ferromagnetic nature of a compound or ion.
• 😑 The value of the effective magnetic moment can vary between different transition metal ions.
• 😑 The effective magnetic moment of Fe3+ ion is 5.91 μB, indicating its paramagnetic nature.
• 😑 The effective magnetic moment of Co2+ ion is 3.87 μB, indicating its paramagnetic nature but with a lower value compared to Fe3+ ion.

Summary & Key Takeaways

• Transition metals have electrons that revolve around the nucleus, which gives them a magnetic moment.

• The magnetic moment is mainly due to the spin motion of the electrons.

• The effective magnetic moment can be calculated using the formula square root of (n + 2) Bohr magneton, where n represents the number of unpaired electrons in the atom or ion.
