Pearson Edexcel IAL Chemistry AS 2.9 Orbitals
Pearson Edexcel IAL Chemistry AS 2.9 Orbitals
Practise the definition of an orbital and how electron spin is shown when two electrons occupy the same atomic orbital.
How this is tested
- define an orbital as a region in an atom holding up to two opposite-spin electrons
- explain paired arrows in an orbital box as electrons with opposite spin
