9 авг. 2019 г. · 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, ... Why does the reactivity of group 7 elements decrease down the ... Does reactivity increase or decrease as you go down group 7? What happens to the reactivity going down group 7? - MyTutor Explain the trend in reactivity of the elements in Group 7. Другие результаты с сайта www.mytutor.co.uk

As 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 ...

The reactivity of elements in Group VII decreases as you move down the group due to an increase in atomic size, an increase in the number of electron shells ...

12 авг. 2024 г. · Reactivity of Group 7 non-metals decreases as you go down the group. However, halogen atoms form negative ions when they gain an electron to obtain a full ...

8 сент. 2017 г. · Because group 7 elements want to gain an electron, they want the most amount of attraction between their nuclei and outer electrons, therefore ... Why does the reactivity of halogens decrease down the group? Why do the group 1 elements get more reactive when they go ... What happens to the reactivity as you go across the periods ...

20 янв. 2018 г. · The halogen reactivity decreases down the group due to the fact the atomic radius increases and shielding increases down the group as the molecules get bigger.

21 сент. 2023 г. · They say that group 7 atoms get less reactive as you go down because while they all have 7 valence electrons.

As, down the group, the amount of electron shielding increases, and the electron becomes less attached to the nucleus.

Halogen reactivities decrease down the group due to an increase in atomic size and a decrease in effective nuclear charge.
