Valence Electrons for d-block Elements (Transition Metals)

Postby Jasmine 2C » Thu Dec 05, 2019 1:59 am

Is there a way to know how many valence electrons transition metals have? And what if it has an oxidation number? How does that affect the number of valence electrons?

Oxidation numbers tell you the charge of the metal and this how many electrons it's missing. So if you have Fe(II), you know that the iron atom is missing 2 more electrons than normal. As far as valence electrons, the transition metals have 3 orbitals (s, p, d). So you can know how many valence electrons the metal has by looking at its location on the Periodic Table and using what we know about orbitals and the arrangement of the blocks on the Periodic Table.
