Lessons

Predicting properties from the groupRead the trends down a group and across a period, then use them to predict the physical and chemical properties of elements you have never studied. 9 min, not started
Deducing an unknown elementTurn a table of melting points, conductivities, oxide pH values and compound formulas into a nature, a group, a period and an identity. 9 min, not started
Finding the group from ionisation energiesSpot the big jump in successive ionisation energies to count outer electrons, name the group and identify the element. 7 min, not started
