The Group 7 Halogens - GCSE AQA Chemistry

In this video we examine the elements found in Group 7 of the periodic table, the Halogens. We also discuss the various different chemical and physical properties of these elements along with examples of reactions they take part in, including displacement reactions.

I'm not very good at writing answers appropriate for the mark scheme. If you were to answer the question " explain the trend in reactivity in halogens" would you mention that they're group 7 or their differences in strengths ? Thanks for the video though, very helpful

Can you pls explain why the halogen reactivity with hydrogen decreases down the group with using bond lenghtt?
