Pearson Edexcel IAL Chemistry AS 3.9 Polarising power & polarisability

Pearson Edexcel IAL Chemistry AS 3.9 Polarising power & polarisability
Pearson Edexcel IAL Chemistry syllabusChemistry YCH11First assessment 2019

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

How this is tested

  • 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
