Question
The species Ar, K+ and Ca2+ contain the same number of electrons. In which order do their radii increase ?
Options
A.Ca2+ < Ar < K+
B.Ca2+ < K+ < Ar
C.K+ < Ar < Ca2+
D.Ar < K+ < Ca2+
Solution
In isoelectronic species
Atomic radius
hence increasing order of radius is Ca+2 < K+ < Ar
Atomic radius
hence increasing order of radius is Ca+2 < K+ < Ar
