d and f BLOCK ELEMENTS Quiz

• Unpaired electrons always make compounds diamagnetic.
• More unpaired electrons decrease paramagnetism.
• Unpaired electrons lead to paramagnetism, while paired electrons lead to diamagnetism.
• Paired electrons increase the magnetic moment.

• They are more reactive than other metals.
• They have larger atomic radii.
• Their crystal structures possess suitable interstitial voids for small atoms.
• They have lower melting points.

• It increases their reactivity.
• It makes their compounds more colored.
• It makes the separation of these elements very difficult.
• It decreases their melting points.

• Their high melting points
• Their ability to form ionic bonds only
• Their ability to adopt multiple oxidation states and form temporary bonds with reactants.
• Their large atomic radii

• They always have paired electrons.
• They contain only s-electrons.
• They frequently contain unpaired electrons in their d-orbitals.
• They lack d-electrons.
