Web1st I.E.: In group 1 and 7 the 1st I.E. is the same. Its harder in Li to remove the electron then is in Cs because the last electron is closer to the Nucleus but in Cs its easier because the valance electron in Cs is much further … WebHow relative atomic mass increase down group 7 and why. Reactivity decreases down the group. This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus.

As you move down group 1 and 7 elements get more …

WebAs you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive.

WebSep 20, 2024 · The atomic radius of atoms generally increases from top to bottom within a group. As the atomic number increases down a group, there is again an increase in the positive nuclear charge. However, there is also an increase in the number of occupied principal energy levels. WebAs you go down the Group, the ease with which these hydrated ions are formed falls, and so the halogens become less good as oxidising agents - less ready to take electrons from something else. The reason that the hydrated ions form less readily as you go down the Group is a fairly complicated mixture of several factors.
