The Importance of d-block Transition Metals

The Importance of d-block Transition Metals By: Daniel Bates The d-block transition metals have great importance in our lives. They are building blocks for life and are found directly in the center of the periodic table. The d-block simply means that the elements’ d-orbitals are the last to get occupied according to the building-up principle.
