Expert Solution

Atomic number of lead is 82 .Hence its electronic configuration expressed with reference to Xe is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p2

Electronic configuration of Hafnium having atomic number of 72 is [Xe ]4f14 5d2 6s2

Arsenic atomic number 33 and its electronic configuration is [Ar] 3d10 4s2 4p3

Scandium atomic number is 21 and its eletronic configuration is [Ar] 3d1 4s2

Silver atomic number is 47 and its electronic configuration is [Kr] 4d¹⁰ 5s1
