What makes an element have a smaller atomic radius the further right on the periodic table you go?

Answer 1

The larger the highest energy level, the larger the atomic radius.

Answer 2

the reason for this is because of the electromagnetic force, where opposite charges attract. The further right you go, the more electron and protons there are, therefore, because protons are in the nucleus (center) and electrons are in the electron cloud (outside the nucleus) the electron cloud is pulled towards the nucleus, making the atom smaller

Answer 3

Using the "shells" model, all the electrons are going into the same shell as you go to the right. The whole shell of electrons are pulled in by their attraction to the protons, and as you go to the right there are more protons, so... they're pulled in more.

Answer 4

As you move to the right on the Periodic Table, the number of protons and electrons increases, resulting in a greater nuclear charge. This increased nuclear charge pulls the electrons closer to the nucleus, reducing the atomic radius. Additionally, the increasing number of electrons also leads to increased electron-electron repulsions, which can further compress the electron cloud.

Answer 5

The atomic radius decreases from left to right. It is because of the nuclear attraction.

Answer 6

The number of electrons increase.

Answer 7

the larger the highest energy level number, the larger the atomic radius (Apex)
