For the alkali metals (Li to Cs) the unit cell lengths of these body-centered cubic crystals are 3.50, 4.28, 5.33, 5.62, and 6.05 A, respectively. Using the Pauli ionic radii , show that the fraction of space outside the core region decreases in going from Li to Cs. What might be the reason for this decrease? What are the plasma frequencies? Pauli Ionic Radii for Li= .60 & Cs= 1.69
