Rank the elements in each of the following sets in order of decreasingIE1:
a, Kr, He, Ar B, Sb, Te, Sn C, K , Ca, Rb d, I, Xe, Cs
Arrange the following elements in order of decreasing first ionization energy:
S, Ca F, Rb, Si
Expert Solution
Step 1: A) and B) sets in order of decreasing IE1
A) Kr, He, Ar
If we go down the group the effective nuclear charge goes on increasing and also and also principal quantum number is increasing.
decreasing order of IE1
He > Ar > Kr
B) Sb, Te, Sn
Valence Electronic configuration
Sb = ns2 np3 ( It is half filled valence electrons orbital more stable.)
Te = ns2 np4
Ar = ns2 np2
decreasing order of IE1
Sb > Te > Sn
