Question

These are 3 elements A, B and C. Their atomic
number are Z, Z2, Zz respectively. If Zz-Z= 2
Z, +Z
and
= Z, and the electronic configuration
2
of element C is (Ar) 3d? 4s2 then correct order of
atomic radius is :-
(1) A+2 < B+3 < C+4
(2) A+2 = B+3 = C+4
> B+3> C+4
(4) B+3 < A+2= C+4
(3) A+2​

Answer 1
