Explore how electrons are arranged around the nucleus of an atom, where the valance electrons are located, and how to predict the number of valence electrons for an element. Related to this Question1) How to find the number of valence shell in the non-transition metals ? 2) How to find ...
Its electronic configuration is 2, 8, 8 So, the number of valence shell (outermost shell) electrons is 8
we observe that the 21st electron occupies the 3d sub-shell. However, as the previously filled 4th shell (4s) has 2 electrons and is apparently the outermost shell, the number of valence electrons is 2.

我猜测最有可能的原因可能是d层和f层和s,p层能级相差太多、e.g. 3d和4s的能级就相差不多、而根据传统定义、只有最外层的才能算valence electrons、所以3d就被排除掉了（虽然这种定义对于解释transition metal的化学性质基本没帮助）、而你的选项valence electrons are all outermost electrons in "a ...
