Group 1 alkali metals
How to think about Group 1
Build the topic from the shared electron feature to reactions and predictions.
- Spot the shared featureGroup 1 elements are alkali metals, and each has a single electron in its outer shell.
- Connect structure to propertiesTheir characteristic properties are linked to this shared single outer-shell electron.
- Know the reaction setFor the first three alkali metals, the reaction contexts to know are oxygen, chlorine and water.
- Follow the trendReactivity increases as you move down Group 1.
- Make a predictionUse the down-group trend to predict that an element lower in Group 1 will be more reactive than one above it.
Three reaction contexts
These are the three reaction partners named for the first three alkali metals.

Each cell hides a short answer and the reason behind it. Predict before you tap.
Group 1 essentials
Keep the vocabulary tight and connected.
