Question

Explain the position of hydrogen in the periodic table on the basis of its electronic configuration.

Answer 1

Hint: In the given question firstly we have to define what exactly is hydrogen and then we can give the proper definition and the characteristics of it. Although we can say that we know that the main points among the following is that it has dual capabilities when compared to different families.

Complete step by step answer:
The given question statement asks about the entire process through which we would be able to get the proper and correct explanation of the hydrogen and the reason because of which it is placed so in the table.
The element of Hydrogen is the chemical element which has the symbol of H and the atomic number of 1. With the given standard atomic weight of the 1.008, we can easily say that the element of hydrogen is also the lightest element in the family of the periodic table. Apart from that the Hydrogen is also the most abundant chemical substance in the universe, constituting roughly 75% of all baryonic mass.
The electronic configuration of hydrogen is $[1{s^1}]$ and due to the imminent presence of the only one electron in its 1s shell we can say that the atom of hydrogen exhibits a behaviour called dual behaviour, i.e., it resembles both alkali metals and halogens.
As a result it is placed at the top of the alkali metals in group 1 & also along the halogens in group 17 since just like halogens,it also requires any one electron to have the configuration of the nearest noble gas element.

Note: In 1671, Robert Boyle discovered and described the reaction between iron filings and dilute acids, which results in the production of hydrogen gas. In 1766, Henry Cavendish was the first to recognize hydrogen gas as a discrete substance, by naming the gas from a metal-acid reaction "inflammable air".
