Abstract:
The atomic dipole polarizability α of the 101 elements from He to No is related to the second ionization potential I₂ and the Waber-Cromer radius r(WC). Our recommended model is the function α = P₁·I₂⁻⁴ + P₂·r(WC)(3) I₂(y). With the parameters P₁ = 2.26, P₂ = 3.912, and y = 0.439, it reproduces the polarizabilities of all 101 elements with a mean absolute deviation of 7.5 au.
