What is wrong with my answer

When main group elements react, they tend to acquire eight outer-shell electrons (ns2np6). This is called an octet, and it is a particularly stable configuration. Nonmetals in the third period and beyond can break the octet rule because they have vacant d orbitals that allow them to accommodate more than eight outer-shell electrons. If the following elements were involved in redox reactions, which noble-gas configuration would they most likely attain? Drag the appropriate elements to their respective bins.

Explanation / Answer

Sc has elctronic configuration of Ar 3d1 4s2
and is most likely to take the noble gas configuration of Argon (Ar)
