Question

An element belongs to the group $VA$ . What would be its valency? Name two such elements.

Answer 1

Hint: The regular arrangement of atoms in the horizontal and vertical tables is known as the periodic table. The earliest known periodic table was proposed by John Wolfgang Dobereiner in the mid ${18^{th}}$ century. This table was said to be Dobereiner triads. The modern periodic table which we today use was given by Henry Moseley in the early ${19^{th}}$ century.

Complete answer:
The periodic table which we use today is the long-form of the modern periodic table, based on the modern periodic law which is as follows: - The physical and the chemical properties of the elements are the periodic functions of their atomic number. This law was given by Henry Moseley in the early ${19^{th}}$ century.
The long-form of the modern periodic table has $18$ groups and $7$ periods. The elements of the S and the P block elements are studied along the group whereas the d block and f block elements are studied along the period.
The series $VA$ is a p block series.
The elements of the group $VA$ have valency $3$ . The elements belonging to this group are also said to be the Pnictogen or Nitrogen family. Examples include, Nitrogen having symbol (N), Phosphorus having symbol (P), Arsenic having symbol (As), Antimony having symbol (Sb), and Bismuth (Bi).

Note:
The periodic table is the backbone of chemistry. We can consider the periodic table to be the home of all the known atoms, in which they are arranged in the order of increasing atomic numbers. Starting with Hydrogen being in the first place and the element named Oganesson being placed in the last with atomic number $118$ .
