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

Consider an electron initially moving in the positive x-direction along the negative x-axis with an energy E. At the origin the electron encounters a square barrier; the potential energy U (x) changes abruptly, from ? U(x)=0? for x<0, to U ( x) 1.0eV for 0<x<a. to U(x)=0 for x>a, where the barrier width a=1 nm . Graph the transmittance as a function of energy, for the range 0 <E<5eV . For what values of energy is there a transmission resonance?
