They can form coloured compounds. They can be used as a catalyst(a chemical that speeds up a reaction). Copper and iron are two common examples. ]]> 2017-12-18 10:27:20 UTC https://padlet.com/fmyall16/jzlqp8axw3lo/wish/216893846 fmyall16 https://padlet.com/fmyall16/jzlqp8axw3lo/wish/216895990 2017-12-18 10:35:44 UTC https://padlet.com/fmyall16/jzlqp8axw3lo/wish/216895990
