Reactivity down group 7

WebExplain why the reactivity of elements increases going down group 1 but decreases going down group 7 Group 1 elements need to lose one electron when they react. As you go down group one there are more energy shells so more distance between the … WebOct 6, 2007 · Why do the reactivity of the group 1 atoms increase as you go down the group, but the reactivity of group 7 decreases as you go down the group. I get why it does in group 1, but I don't get why it does in group 7?? The answer lies in understanding what the atoms are trying to do.

Group 7 (17) - the halogens - chemguide

WebFeb 8, 2024 · The reactivity of Group 7 elements decreases down the group. The electrons in the outer shell move further away from the nucleus as we go down the group and the attraction force between the electrons and the nucleus become weaker and weaker. This weaker attraction in the larger atoms makes it harder to gain electron. WebMar 17, 2024 · The reactivity of Group 7 elements decreases down the group. Non-metal atoms gain electrons when they react with metals. When a halogen atom reacts, it gains one electron into their highest occupied energy level (outer shell) to form a singly negative charged ion.

What are three trends in group 7 elements? - KnowledgeBurrow

WebWhen a halogen atom reacts it will usually gain an electron, to form a 1- ion (X + e- → X-) The oxidation number has decreased from 0 to -1, therefore reduction has occurred. Therefore halogens will act as oxidising agents. Down Group 7 we have seen that the atoms become larger so the outer electrons are further away and are therefore more ... WebAs 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 full shell. As a result, a... WebIn each case, a halogen higher in the Group can oxidise the ions of one lower down. For example, chlorine can oxidise the bromide ions (in, for example, potassium bromide solution) to bromine: Cl 2 + 2Br - 2Cl - + Br 2. The bromine appears as an orange solution. As you have seen above, chlorine can also oxidise iodide ions (in, for example ... incontrolable dalmata english lyrics
