Sparks flying out of a small container. Caption: to form aluminum oxide, leaving iron metal behind.

Science lab experiments demonstrate what happens visibly and at a molecular level with the Group 1 highly reactive metals and the Group 17 highly reactive halogens from the periodic table. Experiments also illustrate the range of reactivity among metals. Video has three 5-minute segments for convenience.
