Group the following electron configurations in pairs that would represent similar chemical properties of their atoms:
- (a) 1s22s22p63s2
- (b) 1s22s22p3
- (c) 1s22s22p63s23p64s23d104p6
- (d) 1s22s2
- (e) 1s22s22p6
- (f) 1s22s22p63s23p3
(a)

Interpretation: The given electronic configurations of the elements have to be grouped, that represent elements with similar properties
Concept Introduction: In the periodic table the elements are grouped based on their valence electrons, so all the elements within a certain group have similar properties. Since only the valence electrons involve in bonding, reactivity of an element depends on the number of electrons present in the valence shell of the atom.
