Question

What is the name of the group \[10\] of the periodic table?

Answer 1

Hint: Modern periodic table contains seven periods and eighteen groups. These groups are also known by the name of the first element of each group. The groups are also called by the name from which the group metals are extracted like alkaline earth metal. Similarly, we will have some common name for the group \[10\] of the periodic table. We will also study the elements of this group.

Complete Answer:
Since we know that the modern periodic table consists of seven periods and eighteen groups. Horizontal rows are known as periods and vertical columns are known as groups. One such group is group \[10\].
The tenth group of the modern periodic table is also known as the group of chemical elements. This group consists of nickel \[(Ni)\], palladium \[(Pd)\], platinum \[(Pt)\] and also the chemically uncharacterized darmstadtium \[(Ds)\]. All these elements of the tenth group are called \[d - \]block transition metals. Since they have their valence subshell is \[d - \]subshell, therefore they are known as \[d - \]block elements. Like other transition metals the elements of this group also show patterns in their electronic configuration. Here the palladium is an exceptional case. These metals are mainly used for decorative purposes. Also they can be used as catalysts in various reactions like hydrogenation of unsaturated compounds.

Note:
They show different physical properties because of variable valency. The atomic number of nickel is \[28\] , palladium is \[46\], platinum is \[78\] and darmstadtium is \[110\]. The electronic configuration of darmstadtium is only a prediction. It is still a matter of research for scientists. All the elements of this group are chemically reactive in nature.
