Webb28 okt. 2024 · the number of valence electrons in d-block elements is most often equal to their group number which is equal to the number of electrons in the "valence shell." for example, scandium metal's electrons per shell are 2,8,9,2 and its outer shell has only 2 electrons, so the valence electron count of scandium is 2. Top 4 posts • Page 1 of 1 WebbA valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Webb9 nov. 2024 · Usually only the electrons in the highest energy level are counted as being valence, but for transition metals, the d-orbital electrons after the previous noble gas configuration count too. For example, for Fe which has an electron configuration of [Ar]3d 6 4s 2, it has 8 valence electrons. Correct me if I'm wrong, though!
