Silver atom has completely filled d orbi...

Silver atom has completely filled `d` orbitals `(4d^(10))` in its ground state. How can you say it is a transition element?

Text Solution

Verified by Experts

According to definition, transition elements are those which have partially filled d-subshell in their elementary state or in their one of the oxidation states. Silver (Z = 47) can exhibit +2 oxidation state in which it has incompletely filled d-subshell (`4d^9` configuration). Hence, silver is regarded as transition element.
