Question:
A cation of a certain transition metal has two electrons in its outermost d-subshell. Which transition metal could this be?
Electronic Configuration of Transition Elements:
The elements that belong to the d-block of the periodic table are called transition elements.
They have their last electron entering the d-subshell and they are called transition elements because they lie between the metallic s-block and non-metallic p-block.
The electronic configuration can be written using Aufbau's principle, Hund's rule, and Pauli's principle.
