Patterns in the Periodic Table
The experiments in this section focus on the patterns in the Periodic Table and include, for example, experiments to explore the properties of the elements and compounds in Period 3.
While we are still at an early stage with this website it's probably more useful to look at the page with our complete list of experiments in alphabetical order. See the list on About this website.
We are starting with GCSE-level experiments.

Experiments
-
Thermal decomposition of metal carbonates
The relative stabilities of a variety of metal carbonates are compared by carrying out thermal decomposition reactions.
-
Solubility patterns among anions of the Group 7 elements
The experiments explore patterns of solubility among the anions of Group 7 elements with lithium, calcium and silver cations.
-
Microscale reactions of chlorine
In this experiment chlorine is produced and reacted with water and halides on a microscale.
-
Reactions of chlorine, bromine and iodine with aluminium
This experiment shows the exothermic reactions which occur when aluminium reacts with the halogens: chlorine, bromine and iodine.
-
Reaction of zinc with iodine
In this experiment students note the differences between a metal and a non-metal, and their reaction to form a metal salt.
-
Liquefying chlorine gas
This experiment shows how easy it is to liquefy chlorine gas by cooling alone.
-
Flame colours – a demonstration
A spectacular demonstration experiment to show the vivid flame colours of a variety of metal salts.
-
Halogen reactions with iron
Demonstration of the reactions of chlorine, bromine and iodine with iron to show the trend in reactivity in Group 7.
