On what ground can you say that scandium (Z= 21) is a transition eleme – InterviewSolution

1.	On what ground can you say that scandium (Z= 21) is a transition element but zinc (Z= 30) is not ?
Answer» Solution :Sc `(Z= 21)` contains incompletely FILLED 3d orbital `( 3d^(1))` WHEREAS zinc contains compltely filled d-orbitals `( 3d^(10))` . Hence, by definition, scandium is a TRANSITIONELEMENT but zinc is not.
