Halogens

This 12-question quiz introduces the halogens, the reactive group of nonmetals found in the periodic table.

You will work through fill-in-the-blank and true or false items, with questions like What is the heaviest halogen? and What halogen is used in bleaching and disinfectant?

A connection to everyday health turns up here too: a shortage of iodine, one of the halogens, is what leads to the swelling condition known as goiter.

You will also compare how reactive the different members of the group are, and learn what compounds they form together.

Recommended level: intermediate.
