Reactivity Definition in Chemistry - ThoughtCo

WebReactivity of elements increases down the group as down the group number of shells increases and thus nuclear pull on the outermost electrons decreases. Solve any question of Classification Of Elements And Periodicity In Properties with:-. Patterns of problems. WebAll group 1 metals have one electron in its outer shell. As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron. Therefore, the … WebWhat is the order of reactivity down the group? Thus, reactivity increases on moving down a group.Thus, the increasing order of reactivity among group 1 elements is as follows: In group 17, as we move down the group from Cl to I, the electron gain enthalpy becomes less negative i.e., its tendency to gain electrons decreases down group 17. marcus signer privat
