Question

Why do atoms get bigger when moving down the periodic table? Pls explain in some detail so i can grasp the concept :(. Pls no copy paste from online

Answer 1

Answer:

As you go down the periodic table, usually atoms get bigger because n gets bigger (there are electrons in higher shells). ... The number of electrons also increases, but they are usually in the same shell or subshell, so the effective nuclear charge increase is more important, and the atoms or ions get smaller going left

Explanation:

Answer 2

Answer:

*This is only my understanding of it*

Explanation:

So basically the positive charge/ the effective nuclear charge on the electrons in the outer most shell decrease because the inner electrons repel the outer electrons, it makes the pull on the on the outer electrons weaker which will result in the increase of the size of the atom.
