Reactivity increases down group 1

WebJan 7, 2024 · Reactivity increases down the group. This is because the outer electron in each atom is further away from the nucleus as you go down the group and so the electrostatic forces between the nucleus and the outer electron are weaker. Subsequently, one may also ask, what is the trend in reactivity in Group 1 with water? WebJun 27, 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.
