What is the relationship between atomic radius, ionization energy, and electronegativity? what is the relationship between atomic radius, ionization energy, and electronegativity? @physics,

Ionization energy is the energy required to remove an electron from a given chemical species. Ionization energy is related to the atomic radiii; such that they are inversely related, therefore ionization increases, atomic radius decrease. Atoms with many electrons get bigger as the electrons become more shielded  from the nucleus. Electronegativity is the atom's chemical ability to attract and bind with electrons. It is the tendency of the atom to attract and form bonds with electrons. Electronegativity increases across the period of elements with decrease in atomic radii, while electronegativity decreases down the period with increase in atomic radii.
