Question

Is Pt a transition metal?

Answer 1

Hint:Pt stands for platinum metal that comes in group 10 and period 6, its atomic number is 78 and its atomic mass or mass number is 195.08 g /mol. The electronic configuration is $[Xe]6{{s}^{1}}5{{d}^{9}}$.

Complete step-by-step answer:There are many elements in the universe, which are arranged in the periodic table. There are parts in the periodic table, i.e., representative elements, transition elements, and inner transition elements.
The representative elements are placed on the left and right side of the periodic table which are s-block and p-block elements. The middle part of the periodic table contains transition elements that are known as d-block elements. In the lower part of the periodic table are the inner transition elements that are f-block elements. The elements are based on the different groups by the entrance of the last electron in the shell.
Pt stands for platinum metal that comes in group 10 and period 6, its atomic number is 78 and its atomic mass or mass number is 195.08 g /mol. The electronic configuration is $[Xe]6{{s}^{1}}5{{d}^{9}}$.
So, as we can see that the last electron enters the d-orbital, which means it is a d-block element. But the electronic configuration of platinum is an exception because without the extra stability of the d-orbital still, one electron from the s-orbital jumps to the d-orbital.
Therefore, platinum is a transition element.

Note:Platinum is a metal that comes in the category of unreactive metal. It is a precious and silverfish-white transition metal. The properties of this metal are dense, malleable, and ductile.
