9 мая 2020 г. · 3d is not the outermost shell but after losing own electron. Sc(+3) gets inert gas configuration and it is more stable than in +2 oxidation state. How many valence electrons does scandium have? Why does scandium's third shell have 9 electrons? Другие результаты с сайта www.quora.com

28 сент. 2022 г. · Because there is 1 electron in the 3d orbital and 2 electrons in the 4s orbital, 1 + 2 = 3 valence electrons that are easily mobilized and can form bonds.
