trends in the halogens

Trends in Chemical Reactivity - Some important group trends are: (a) On account of high ionization enthalpies, simple M 4 + ions of the group are not known. (b) Unlike carbon the other elements of the group form compounds having coordination numbers higher than 4 like (SiF 5 ) -..

Chemical reactivity of halogens - The halogens are the most reactive elements as a family. Fluorine is the most reactive of all the halogens. The reactivity of the halogens decreases down the group. The high reactivity of halogens is due to the foll..

As we move down a group the atomic size and nuclear size increases. As the effect of increase in atomic size is more pronounced the additional electron feels less attracted by the large atom. Consequently the electron affinity decreases. However there are some irregularities observed in the above ..
