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

The amount of attraction for electrons defines ____.

• ionization energy

• atomic radius

• metallic character

• electronegativity

Electronegativity increases toward ___.

• fluorine

• francium

• hydrogen

• oganesson

Electronegativity increases to the right because the addition of ___

• electrons increases the pull of the nucleus

• energy levels increases the pull of the nucleus.

• edges of the electron cloud

Atomic radius increases toward the ____ corner of the PT.

• top right

• top left

• bottom left

• bottom right

Atomic radius increases moving down any group because of the addition of ___.

• valence electrons
