Atomic radii decrease, however, as one moves from left to right, across the Periodic Table. Although more electrons are being added to atoms, they are at similar distances to the nucleus; and the increasing nuclear charge "pulls" the electron clouds inwards, making the atomic radii smaller.

Therefore, the attraction between the positive nucleus and negative electrons in the outer shell increases, so the atomic radius (the distance between the nucleus and the outer shell) decreases. Explain the position and numbering system of elements on the periodic table.Atomic radii increases moving down a group in the periodic table due to the increasing energy levels in the electron configuration and electrons filling in energy levels further away from the nucleus. The atomic radius increases as we go down the group as the number of shell increases down the group.
