Question

Which among the following elements have lowest value of IE1 ? (A) Pb (B) Sn (C) Si (D) C

Tardigrade Admin · Accepted Answer

The ionisation energy of Tin (Sn) is less than that of lead (Pb). It is due to the poor sheilding of d- and f- electron in Pb due to which it feels greater attraction from nucleus.
