Pearson Edexcel IAL Chemistry syllabusChemistry YCH11First assessment 2019
Practise writing and recognising electronic configurations for atoms and ions using s, p, d notation and electron-in-box diagrams.
How this is tested
- write full or shorthand s, p, d configurations for atoms and ions up to krypton
- select electron-in-box diagrams that match ground-state filling and spin rules
- remove 4s electrons before 3d when forming transition-metal ions
