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. WebThe reactivity of the group 1 metals increases as you go down the group; When a group 1 element reacts, its atoms only need to lose the 1 electron in the outer shell When this happens, 1+ ions are formed; The next shell down automatically becomes the outermost shell and since it is already full, a group 1 atom obtains noble gas configuration

WebAn alternative flowchart to explain why reactivity increases down Group 1 Flowchart adapted from: K. Taber, Chemical misconceptions – prevention, diagnosis and cure, London: Royal Society of Chemistry, 2002 This example highlights the introduction of an additional concept to the line of reasoning – ie the WebTrend in reactivity in a group can be explained using the electronic structure of atoms. Looking at the reactions discussed beforehand, when going down group 1 the reactions get more and more vigorous. This suggests that as you go down group 1, the reactivity of the elements increases. crystal run health care + west nyack ny
