WebOct 12, 2024 · D-block metals are also more commonly referred to as transition metals. Transition metals are highly colored metals due to their partially filled d-orbitals, which can hold a maximum of 10 electrons. WebMetals with one valence electron tend to be soft. Metals with more valence electrons and transition metals are harder. D-block electrons are delocalized in a metallic bond, as well as s-block electrons. The more s and d block electrons in a metal, the harder it will be.
