On the basis of electronic configuration, how will you identify:

(i) chemically similar elements ?


(ii) the first element of a period ?

(i) The elements whose valence shell electrons are same, it means that those elements have similar chemical properties.

(ii) The first element can be identified by checking its valence shell electrons, elements which have 1 electron in their valence shell then these elements are the first element of the period.
