Another way to find an element's valence electrons is with something called an electron configuration. Learn how to read an electron configuration. This means that an atom can have multiple numbers of valence electrons depending on how it is manipulated. For reasons that are a little too complex to explain here, when electrons are added to the outermost d shell of a transition metal (more on this below), the first electrons that go into the shell tend to act like normal valence electrons, but after that, they don't, and electrons from other orbital layers sometimes act as valence electrons instead.Generally, the valence electrons are the electrons in the outermost shell - in other words, the last electrons added. As electrons are added to an atom, they are sorted into different "orbitals" - basically different areas around the nucleus that the electrons congregate in.See below for a quick run-through or skip this step to get right to the answers. Understanding why transition metals don't really "work" like the rest of the periodic table requires a little explanation of the way electrons behave in atoms. You can effortlessly find every single detail about the elements from this single Interactive Periodic table.Understand that transition metals don't have "traditional" valence electrons. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ).

If you want a Periodic table with Valence electrons, then visit Periodic table with Valence electrons labeled in it. But for most of the transition and inner transition elements, the valence electrons are the electrons present in the shells outside the noble gas core.For main group elements (i.e s-block and p-block elements), the valence electrons are the electrons present in the outermost orbit.
