How does effective nuclear charge change across a period and down a group

increases in a period, decreases down a group

How does shielding change across a period and down a group

Does not change across a period, increases down a group

How does atomic radius change across a period and down a group?

Decreases across a period, increases down a group

How does electronegativity change across a period and down a group

Increases across a period, decreases down a group

How do the sizes of cations differ from the atoms they form from?

They are smaller than their parent because they have less electrons, so they are more drawn towards the nucleus.

How do the sizes of anions differ from the atoms they form from?

They are larger than their parent because they have more electrons, so they have a stronger repulsion which moves them further from the nucleus.
