(a) What properties in the table are typical of … WebAug 3, 2024 · Iodine is lower down in group 7 and therefore less reactive than chlorine and bromine. Iodine is not able to displace either of these halogens, so no colour change is seen as no displacement reaction happens. These observations show a trend in the reactivity of the halogens. As you go down through the halogens, the reactivity decreases.
WebYou need to know a little about several of these groups, particularly groups 1, 7 and 0. These have 'trivial names' - the alkali metals, the halogens and the noble gases. The patterns in the periodic table are usually referred to as trends because the patterns are not exact and in some cases, you can't measure them directly e.g. reactivity of the alkali metals with water. WebAs you go down group 7, reactivity of the halogens decreases because: The atomic mass of the halogens increases. They increase in electron shells; so the atoms are larger as you go down the group. Therefore, the attraction of the outer electron to the nucleus decreases as you go down group 7.
