Classificaion of Scandium and Zinc are not transitional metal base on their general chemistry and properties

Introduction
The three series of elements situated in the periodic table following the alkaline earth metals are described as transition metal; this term is sometime extended to include the lanthanide and actinide elements.
There position in the periodic table is between the s-block and p-block elements, their properties are transitional between the highly reactive metallic elements in the s-block, which typically form ionic compounds, and the elements of the p-block, which are largely covalent. In the s- and p-block electrons are added to the outer shell of the atom, in the d-block el…
