Down-group trends in the p-block
Down-group trends in the p-block
The p-block contains elements whose highest-energy electrons occupy a p sub-shell. In this topic, Group 3, 4 and 5 correspond to the modern Groups 13, 14 and 15, and down a group atoms get larger while ionisation energy generally decreases.
Step-by-step lessons covering Eduqas A Level Chemistry Chemistry of the p-block for A Level Chemistry. Each lesson works through exam-style questions in Component 1, Component 2 and Component 3 format. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
