What trends do we see on the periodic table for atomic radii, ionic radii and electronegativity?
Let me explain,
Atomic radii decrease as electronegativity increases in a left-to-right period.

Atomic radii generally decrease across a period and increase down a group on the periodic table. Ionic radii follow a similar trend, decreasing across a period and increasing down a group. Electronegativity increases across a period and decreases down a group.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
