Gallium melts in your hand, an aluminium can does not rust, and boric acid is safe enough for an eyewash. We read the trends of group 13, see why boron is the odd one out, and study borax, boric acid, diborane and the compounds of aluminium.

Created by StemPy LabA drinks can, a gem and a metal that melts in your hand all come from group 13. We read the trends of the group, and see why boron behaves so differently from the rest.
A glassware shelf, an eyewash and a rocket fuel idea all lead to boron. We look at the structure of borax, the layered crystal of boric acid, and the strange bonds of diborane.
A drinks can, a window frame and an aeroplane are made of aluminium, yet the metal was once rarer than gold. We follow it from the ore to the metal and meet its oxide, its hydroxide, its chloride and the alums.
