d and f BLOCK ELEMENTS Quiz

• High thermal conductivity
• High electrical conductivity
• Metallic lustre
• High volatility

• They are always in aqueous solution
• They have partially filled d subshells
• They absorb all wavelengths of visible light
• They have either empty (Sc³⁺) or full (Zn²⁺) d subshells, preventing d-d transitions.

• +2
• +4
• +6
• +7

• They always lose all their d-electrons first
• They have very low ionization energies for all electrons
• The energy levels of (n-1)d and ns orbitals are similar, allowing electrons from both to be involved in bonding.
• They only gain electrons
