Which of the following sentences is the most accurate 0 The polarizability a of an atom or nonpolar molecule quanties the dipole moment induced by the electric eld at the site of an atom or nonpolar molecule, such that p 2 LEE A rough approximation for the polarisability is o.- = 471'an3 where a is the radius of the atom. O The polarizability of an atom quanties the dipole moment induced by the electric eld at the site of the atom, such that p 2 GE. This equation is exact. and the polarizability is given by 0: = 4'Ega3. O The polarizability of an atom quanties the dipole moment induced by the electric eld at the site of the atom, such that p 2 0E. For all atoms we have c: = 41759113. 0 The polarizability of an atom quanties the dipole moment induced by the electric eld at the site of the atom, such that p = 01E. a is the same for every atom
