WebOct 11, 2024 · Why does atomic radius increase down a group class 11? Atomic size increases down the group because of the addition of extra shells. So, as we move from group 1 to group 18 the size of the atom will decrease due to … WebLooking at group 1 for example, it seems that Zeff remains the same at 1 (i.e., the increase in number of shielding electrons is negated by the increase in protons), and consequently atomic radii increases. The nuclear charge does in fact increase down a group but the shielding effects of additional electrons counters the attractive force.

WebAcross a period, effective nuclear charge increases as electron shielding remains constant. This pulls the electron cloud closer to the nucleus, strengthening the nuclear attraction to the outer-most electron, and is more difficult to remove (requires more energy). Down a group, the number of energy levels (n) increase and the distance is ...
