The elements in this group include some of the most common and useful ones on the planet - and they probably all wish they weren’t associated with francium. Sitting at the bottom of this row of ...

Nevertheless, the fact that the francium atom has the largest diameter of any element, at a huge 2.7 ångströms, and the fact that it has just one outer-shell electron, has made it the object of ...
