Webfluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Its chemical activity can be attributed to its extreme ability to attract … WebGroup 7 of the periodic table contains all the elements known as halogens. They all have 7 valence electrons (hence group 7!) in their outer shell (insert diagram or prop to show what the outer shell signifies).Fluorine has a higher electronegativity than Chlorine because it has one shell less than Chlorine.

Fluorine - Periodic Table

WebFluorine is the most reactive element in the periodic table, forming compounds with every other element except helium, neon, and argon. The reactions of fluorine with most other elements range from vigorous to explosive; only O 2, N 2, and Kr react slowly. There are three reasons for the high reactivity of fluorine: WebHalogens as Oxidising Agents. This page explores the trend in oxidising ability of the Group 7 elements (the halogens) – fluorine, chlorine, bromine and iodine. We are going to look at the ability of one halogen to oxidise the ions of another one, and how that changes as you go down the Group. Note: If you aren't comfortable with terms like ...
