What trend for the reactivity of metals do we see going down a group? Why do we see this trend? What evidence do we have for this trend? by Rebecca Adcock https://padlet.com/radcock/wphsv627h1ms en-us 2018-03-06 18:03:42 UTC 2025-11-09 06:09:29 UTC hello@padlet.com KC https://padlet.com/radcock/wphsv627h1ms/wish/238831379 Reactivity increases as you go down a group and the evidence is our lab yesterday. ]]> 2018-03-06 19:09:41 UTC https://padlet.com/radcock/wphsv627h1ms/wish/238831379 https://padlet.com/radcock/wphsv627h1ms/wish/238831646

This means it easier for elements to lose electrons and undergo a reaction. As you go down a group, elements react stronger and quicker.
