Which of the following statements is false?
Electron affinity is a measure of the energy evolved when a
gaseous atom gains an electron
Anions are smaller than the parent atoms from which they are
derived
Ionization energies decrease as the atomic radius
increases
For isoelectronic cations, the higher the charge, the smaller
the ion
Cations are smaller than the parent atoms from which they are
derived
