Lessons

Halogens as oxidising agentsThe halogens gain electrons to form halide ions, and their oxidising power falls down Group 17, which displacement reactions reveal. 6 min, not started
Halogens and hydrogen: from explosion to persuasionFluorine and hydrogen react explosively, while iodine needs heat and still gives little product, because the H–X bond gets weaker down the group. 6 min, not started
Which hydrogen halide survives the heat?HF is stable, HI falls apart easily, and the reason is the strength of the H–X bond. 5 min, not started
