Researchers have long been hunting for a way to make the elusive elements more stable so they can be better studied.

The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group.

Group 1 elements react with moist air. They are stored in oil to stop air and water vapour coming into contact with them. Moist air reacts with potassium to form potassium oxide. This creates a ...

The men define ‘composition requirements’ as Element Groups in their Code of Points. If all the requirements are included, a maximum of 2.5 points are rewarded. Vault is the only apparatus that has a ...
