WebAs we descend Group 7, the reactivity decreases. For stability, the atom needs to have a full outer shell. Group 7 elements need to gain 1 electron to have a full shell. WebReactivity increases down the group: 5, 6, 7: Non-metal: Reactivity decreases down the group: An explanation of the patterns of reactivity in group 1 and 7 elements in the periodic table
WebHow does the chemical reactivity change as we move down in group 17 of the periodic table? The tendency to gain electron decreases down the group due to increase in atomic radii and a decrease in the effective nuclear force. Why does the reactivity decrease down group 7? Reactivity decreases down the group. WebThe fall in reactivity is because the halogens become less good oxidising agents as you go down the group. In the cases of chlorine and bromine, the iron atoms are oxidised to iron (III) ions. Electrons are removed by the chlorine or bromine. Fe Fe 3+ + 3e - But with iodine you only get iron (II) ions. Fe Fe 2+ + 2e -

The reactivity is related to the oxidising power of the halogens, which decreases down the group. tofield canadaWebJan 8, 2024 · The chemical reactivity of group 17 elements decreases down the group. So down the group there is an increase in the atomic radius and hence the effective nuclear force decrease as the atomic radius increases and this leads to the decreased chemical reactivity down the group. people hr gdprWebThe reactivity of halogen family decreases as we move down the group. Halogens readily accept electrons as they are short of one electron to form an octet. Hence, they have strong oxidizing nature. Fluorine is the … tofield chinese foodWebApr 7, 2024 · The reactivity of the halogens decreases down the group. The high reactivity of halogens is due to the following reasons : (i) Low dissociation enthalpies All the halogens have very low dissociation enthalpies. As a result, they can readily dissociate into atoms and react with other substances. (ii) High electron gain enthalpy tofield community garage saleWebOct 6, 2007 · This is best when the atom is as small as possible and so fluorine is the most reactive of the halogens.
