The Periodic Table
Describe the organisation of the periodic table into periods and groups, explain the contribution of Mendeleev, and use the table to identify metals, non-metals, and predict patterns in reactivity
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.

If your child was looking at a periodic table, could they explain why elements in the same column tend to behave similarly — and say what Mendeleev did that made it so useful to chemists?

Check understanding
- Explains why the periodic table is arranged into periods (rows) and groups (columns)
- States that elements in the same group have similar chemical properties
- Locates metals, non-metals, and metalloids in the periodic table
- Explains how Mendeleev ordered elements by atomic weight and predicted missing elements
