As you move down group 7 from fluorine to iodine, the reactivity of the elements decreases. The halogens are non-metals and when non-metals react with metals, ...

The Halogens decrease in reactivity as you descend through the group. The atoms increase in size and Mr as you go down the group. Therefore their outer ...

As you go down the group, the outer electrons are further from the nucleus, this leads to a reduced attraction between the negative outer electrons and ...

This is because the size of the halogen atom increases down the group, meaning there is increased electron shielding. Therefore, the nucleus of halogen atoms ...

The group 7 elements become less volatile as you go down the group. This is because as you go down the group the molecules become larger and contain more ... Не найдено: reactivity | Нужно включить: reactivity

The melting points and boiling points of the halogens increase as you go down the group. This is because larger molecules within the same group experience ... Не найдено: reactivity | Нужно включить: reactivity

The electronegativity of the halogens decreases down the group as the radius of each atom increases due to more shells. This means there is less attraction ... Не найдено: reactivity | Нужно включить: reactivity

The reducing ability of halide ions increases as we go down the group because the size of the ions increases down the group. Не найдено: reactivity | Нужно включить: reactivity

Group 7 elements are less reactive down the group because the electron shells have a repulsive effect on the reacting electron, which weakens the force of ... Не найдено: halogens | Нужно включить: halogens

The magnitude of London forces is proportional to the mass of the molecules, so as the molecular weights of the halides increase down the group, more energy is ... Не найдено: reactivity | Нужно включить: reactivity
