WebMay 2, 2016 · The bond enthaply of halogens decreases down the group so why is the reactivity of halogens with hydrogens decreases down the group? ... Bond Energy trends are a function of electronegativity in series and of ionic size in groups. In series (consider Series II => Li, Be, B, C, N, O, F & Ne). Electronegativity increases with increasing atomic ... WebTrends of Chemical Reactivity in Periodic Table Conclusion Identical chemical properties are shared by the elements arranged in periodic table groupings (vertical columns). Members of a group have the same number and distribution of electrons in their valence shells, resulting in this resemblance.
