d and f BLOCK ELEMENTS Quiz

• Exchange energy
• Kinetic energy
• Potential energy
• Electron affinity

• The second electron is always a d-electron
• The second electron is removed from a positively charged ion, experiencing a higher effective nuclear charge
• The atomic radius increases after the first ionisation
• The second electron is in a lower energy level

• It causes the atomic radii to increase significantly
• It causes the atomic radii to decrease only slightly across the transition series
• It has no effect on atomic radii
• It causes fluctuations in atomic radii

• Weak van der Waals forces
• Strong metallic bonding involving delocalised d-electrons results in strong interatomic forces
• They form covalent network structures
• They have low atomic masses

• It is the most unstable configuration
• It represents a particularly stable arrangement that influences ionisation energies and compound stability
• It is only found in chromium
• It has no special significance
