Pearson Edexcel IAL Chemistry 3.9 Polarising power & polarisability

Practise comparing polarising power and polarisability from ion size and charge, then linking them to covalent character.

Level

Exam points

  • identify the most polarising cation from small radius and high positive charge
  • explain anion polarisability by linking large radius or higher charge to electron-cloud distortion
  • predict greater covalent character from a strongly polarising cation and polarisable anion

3.9—The polarising power of a cation depends on its radius and charge, and the polarisability of an anion also depends on its question 1
