Ionization energy is the energy needed to

• attract electrons

• remove electron(s)

• increase an atom's radius

• increase metallic character

Ionization energy increases on the PT toward

• the top right corner

• top left corner

• bottom right corner

• bottom left corner

Ionization energy increases toward the right across a period because the increasing numbers of _____ making it harder to remove electrons

• energy levels increases the pull toward the nucleus

• valence electrons

• protons increases the positive pull of the nucleus

• atomic radius
