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 ...

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? Explain the trend in reactivity of the elements in Group 7. What happens to the reactivity going down group 7? - MyTutor Другие результаты с сайта www.mytutor.co.uk

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 ...

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 ...

The name 'halogen' means 'salt-producing' because halogens produce a range of salts when they react with metals. – get less reactive as you go down the group.

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.

Reactivity decreases down the group. This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding ...

27 мар. 2024 г. · Reactivity decreases because: Going down the group, the number of shells increases. The outer shell is therefore further away from the nucleus.
