Trends in Atomic Radius and Ionisation Energy

Trends in Atomic Radius and Ionisation Energy

The elements in Group 2 of the periodic table, from magnesium (Mg\text{Mg}Mg) to barium (Ba\text{Ba}Ba), are known as the alkaline earth metals. As you move down the group, their physical properties show distinct trends due to changes in their atomic structure. Specifically, the atomic radius increases as you go down Group 2.

Step-by-step lessons covering AQA A Level Chemistry Group 2, the alkaline earth metals for A Level Chemistry. Each lesson breaks down Group 2, the alkaline earth metals, then works through exam-style questions in Paper 1, Paper 2 and Paper 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.
