4.Which set of quantum numbers is possible for the last electron of Mg ion?[1](A) 1=1, I=0, m=0, s=+/(C) n=3, 1=0, m=0, s=+'/(B) n=2, l=1, m=0, s=+/(D) n=3, 1=2, m=0, s=+/2.40

Answer»

option c is correct beacuse the principle quantum number of mg is 3 and as it belong to s block so the azimuthual quantum number for mg is 0 and for magnetic quantum number is also 0
