Web29 dec. 2024 · The number of valence electrons available for the Scandium atom is 3. Scandium is situated in the transition metal group and has an atomic number of 21. The orbital diagram for Scandium is drawn by following three principles – the Aufbau principle, Hund’s principle, and Pauli’s exclusion principle. WebImagine you are building a scandium atom from boxes of protons, neutrons and electrons. You have built the nucleus from 21 protons and 24 neutrons, and are now adding electrons around the outside. So far you have added 18 electrons to fill all the levels up as far as 3p. Essentially you have made the ion Sc 3+. Making Sc2+
