WebMar 19, 2024 · They denote the atom’s primary electron shell. Because it describes the most likely distance between the nucleus and the electrons, a larger value of the principal quantum number implies a greater distance between the electron and the nucleus (which, in turn, implies a greater atomic size). WebOct 16, 2024 · We know that (i) atomic radius decreases ACROSS a Period from left to right as we face the Table; and (ii) atomic radius INCREASES down a Group, a column of the Periodic Table. Why? Well, atomic size depends on electronic radius, and INCOMPLETE electronic shells shield the nuclear charge very ineffectively.

WebOr is it because protons have a greater force of attraction compared to the repulsion force between electrons? atomic-radius; Share. Improve this question. ... Atomic size across a period, in fact, has everything to do with electron shielding and the effective nuclear charge (charge felt by the electrons). ... WebA higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. 2.

WebThe increase in atomic size going down a column is also due to electron shielding, but the situation is more complex because the principal quantum number n is not constant. As we saw in Chapter 6 "The Structure of …
