Question

Zinc and mercury do not show variable valency like d-block elements because (A) They are soft (B) Their shells are complete (C) They have only two electrons in the outermostshell (D) Their d-shells are incomplete

Tardigrade Admin · Accepted Answer

Zinc and mercury donot show variable oxidation state (or valency) like other d-block elements, because their d-subshell is fully filled or complete
