WebWhen we move down a group in the periodic table, more energy levels are added, and so valence electrons would become further and further away from the positive nucleus. This causes the attraction between valence electrons and the nucleus to decrease, something known as the shielding effect. WebWhile they amount of protons do increase and draw the electrons in, the way the electrons extend outward in a shell formation makes the atom bigger. The electrons in the outer layer are repelled by electrons in the innermost layers (negative and negative repel), producing a large amount of layers like an onion. 2 comments ( 6 votes) Upvote Downvote

WebIn the table above, most of the atomic radii listed are average atomic radii, while for the halogens (Group 7A) and the noble gases (Group 8A) the covalent radius is used. Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and ... WebSep 11, 2024 · Therefore the closer the electron to the nuclear the higher the attraction force, and thus the higher the energy required to overcome this attraction and remove the electron. Therefore the smaller the radius the higher the ionization energy, and the bigger the radius the lower the energy need. Answer link

WebIonization energies increase across a period (ie, as you move across a row in the periodic table). This is because the positive charge of the nucleus increases whilst the electrons remain at the same average distance, this makes it more difficult to pull an electron away from the nucleus and hence the ionization energy decreases.
