Why does scandium have 9 electrons?
Answer: Every element adds one more electron to the outermost shell. Instead of having three electrons in the outer shell, scandium adds its electron to the second to last shell. The electron configuration is 2-8-9-2.
Why is scandium electron configuration?
Therefore electronic configuration of scandium(Sc) is: 1s2 2s2 2p6 3s2 3p6 3d1 4s2. Here, two electrons are in 4s orbital instead of being in 3d orbital because 4s orbital is having lesser energy than 3d orbital and 4s orbital also gives full-filled stability which 3d can not give.

How many orbitals does the d subshell have for scandium?
Each d subshell holds at most 10 electrons(5 orbitals)
Why scandium is not a transition element?
A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals. On the basis of this definition, scandium and zinc do not count as transition metals – even though they are members of the d block. … The Sc3+ ion has no d electrons and so does not meet the definition.
