Question
Sodium forms Na+ ion but it does not form Na2+ because of
Options
A.very low of 1 st and II nd I.E.
B.very high value of I st and II nd I.E.
C.High value of I st I.E. and low value of II nd I.E.
D.Low value of I st I.E. and high value of II nd I.E.
Solution
Na(Z = 11 ; 1s2, 2s2 p6, 3s) readily gives one electron because the resulting
Na+ (1s2, 2s2, p6) Has stable configuration. Thus the first IE of Na less. Hower, removal of an electron from a stable (noble gas) configuration requirs high energy and Thus IE2 of Na will be very high.
