WebMar 23, 2024 · For main group elements (i.e s-block and p-block elements), the valence electrons are the electrons present in the outermost orbit. 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. WebAnswer (1 of 11): If it's neutral, then it'll have the properties of a metal and its number of electrons will equal to its protons or its atomic number. So the answer would be 12. But if you're talking about magnesium in the sea or magnesium in rocks …
