(a)
Anions are bigger/smaller than their neutral atoms.
(a)
Put in order from smallest to largest radius: Mg, Si, S, or Na.
Put in order from smallest to largest radius: He, Xe, Ar.
Put in order from low to high electronegativity (EN): Al, Ne, Ca, Se.
Put in order from low to high ionization energy (IE): I, Cr, Rb, N.
Cations (+) are smaller than their atoms since you are removing valence electrons that are farther from the nucleus and anions (−) are larger than their atoms since adding extra electrons increases electron-electron repulsions.
True
False
