Volume of  Lithium (1s22s1) = 43πr3                         = 43 × 3
14 × (1
23)3                     = 7
79 A0Volume of Li+ (1s2) = = 43πr3                         = 43 × 3
14 × (0
76)3                     = 1
84 A0Thus the volume of the 2s electron = 7
79 - 1 84 = 5
95 A0% of volume occupied by single valence electron = 5
957 79 × 100 = 76
38 %

Atomic radius of Li is 1.23 A0& ionic radius of Li​+ is 0.76 A0.Calculate the percentage of volume occupied by single valence electron I.e , 2s electrons.

Atomic radius of Li is 1.23 A⁰& ionic radius of Li^⁺is 0.76 A^0.Calculate the percentage of volume occupied by single valence electron I.e , 2s electrons.
