Answer 1

1)ZINC ATOMIC NUMBER IS (Z)=30

THE ELECTRONIC CONFIGURATION IS 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰

2) Iron atomic number is (Z)=26

THE ELECTRONIC CONFIGURATION IS 1s²2s²2p⁶3s²3p⁶4s²3d⁶

IN THE ABOVE CONFIGURATION 1s²2s²2p⁶3s²3p⁶ represents noble gas ARGON (Ar)

therefore using noblegas notation the electronic configuration of iron atom is [Ar]4s²3d⁶
