Hint: Every element which is present in the periodic table is placed in a position based on their number of electrons, physical and chemical properties. According to the properties of the chemical elements, the periodic table is divided into blocks.

Complete answer:
- In the question it is asked about the position of the scandium in the periodic table.
- First, we should know about the atomic number of the scandium to know about the position of it in the periodic table.
- The chemical symbol to represent the chemical element scandium is Sc.
- The atomic number of the scandium is 21 means scandium contains 21 electrons in their atomic orbitals.
- Scandium is a silvery white color element with 21 electrons in its electronic configuration.
- The electronic configuration of the Scandium is as follows.
\[1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{1}}\]
- By knowing the electronic configuration of an element also we can find the position of the element in the periodic table.
- The last electron in the scandium is going to enter the d-orbital as we can in the above-mentioned electronic configuration.
 -Therefore, the scandium element is present in the d-block of the periodic table.

Note:
By knowing the electronic configuration we can find the position of the chemical element in the periodic table. Without knowing the atomic number and the electronic configuration of an element it is very difficult to find the position of the chemical element in the periodic table.
