Reactivity up and down a group - Revision World
WebNov 7, 2015 · The answer to your question is quite simple.The alkali metals of group 1 grow larger in size downwards and since the effective nuclear charge remains the same as we go down group 1 the number of shells also increases and so it is easy to lose an electron and therefore as we move downwards the reactivity increases. However in group 17 the ... WebJan 25, 2024 · Because of this, they are more reactive than other non-metal groups.
