How does atomic radius generally change as you move left to right across a period?

It first increases then decreases

How does atomic radius generally change as you move down a group (column)?

It first decreases then increases

How does first ionization energy generally change as you move down a group?

It first increases then decreases

How does electronegativity generally change across a period from left to right?

It peaks in the middle of the period

Why does atomic radius generally decrease across a period?

Because electrons are added to new, larger shells

Because nuclear charge increases, pulling electrons closer

Because atoms gain protons and lose electrons

Because shielding increases significantly across a period
