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 ... Explain the trend in reactivity of the elements in Group 7. Другие результаты с сайта www.mytutor.co.uk

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.

3 мая 2016 г. · As the atomic number increase, the reactivity decreases. That is because each one of them 'wants' to complete their outer electron shell by adding one electron. Why does the reactivity increase down the group in 1A, but ... What happens to the reactivity of halogens as we go down the ... Why does reactivity decrease down in Group 17 of the periodic ... Why do the reactions of halogens with hydrogen become less ... Другие результаты с сайта www.quora.com

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

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.

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.

22 окт. 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 ...
