Down a group in the periodic table, the change in ionization energy is

due to what?

• valence electrons being further from the nucleus

• increasing charge of the nucleus

• valence electrons being closer to the nucleus

• decreasing atomic radii

What is atomic radius?

• the size of an atom

• the energy required to remove an electron from an atom

• the ability to attract electrons from other atoms

• how far an electron travels past orbit

Why does atomic radius generally decrease as you move across a period?

• increased nuclear charge as you gain protons

• increased negative charge as you gain electrons

• increased gravitational force as the size changes

• the atom collapses due to decreased mass
