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, ...

Reactivity will decrease as you travel down group 7 in the periodic table. Group 7 elements need to gain an electron to become stable as they need 8 electrons ...

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

The reactivity decreases down group 7 as the atomic radius increases, as the distance between the outer shell electrons and nucleus increases.

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 ...

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 ... Не найдено: increase | Нужно включить: increase

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 ...

Going down Group 7 in the period table, the mass number increases, so the element becomes heavier. The period increases so the number of shells increase. 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 ...

All 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.
