The electronic configuration of four elements are given below. Which elements does not belong to the same family as others ?
Options
(a) [Xe]4f¹⁴5d¹°1s²
(b) [Kr]4d¹°5s²
(c) [Ne]3s³3p⁵
(d) [Ar] 3d¹°4s²
Correct Answer:
[Ne]3s³3p⁵
Explanation:
Elements (a), (b) and (d) belong to the same group since each one of them has two electrons in the s sub shell. In contrast, element(c) has seven electrons in the valence shell and hence does not lie in the same group in which elements (a), (b) and (d) lie
