Question

Hydrogen accepts an electron to form an inert gas configuration. In this it resembles
A. Halogen
B. Alkali metals
C. Chalcogens
D. Alkaline earth metals

Answer 1

Hint: Hydrogen is a gas which has no odour, colour, or taste. A Hydrogen atom carries a nucleus consisting of a proton, and an electron, revolving about the nucleus.

Complete Step by Step Answer:
The atomic number of Hydrogen is 1.
Hydrogen has an uncomplicated atomic structure among all the elements around us in nature.
In atomic form, it has only one proton and one electron. Nonetheless, in elemental form, it exists as a diatomic molecule and is known as dihydrogen.
It constitutes more compounds than any other element. Hydrogen is the first element in the periodic table.
Hydrogen has electronic configuration \[1{s^1}\].
If hydrogen gains one electron its electronic configuration will be \[1{s^2}\] which is the electronic configuration of Helium.
Here in this question, it is given that if Hydrogen accepts an electron to form an inert gas configuration, we have to answer that in this it will resemble which type of element.
The noble gas elements are stable and inert as the outer valence shells are filled with eight electrons.
So, every element tries to attain a noble gas configuration to be stable.
We know that halogens accept one electron to attain noble gas configuration.
It is because, after the halogen group, the noble gases group comes.
The halogens thus accept one electron to attain a stable noble gas configuration.
So, Hydrogen accepts an electron to form an inert gas configuration. In this it resembles Halogen.
So, option A is correct.

Note: The arrangement of hydrogen in the periodic table is the topic of conversation till now. We know that the arrangement of elements in the periodic table is according to their electronic configurations. The electronic configuration of hydrogen is identical to the outer electronic configuration (\[n{s^1}\]) of alkali metals which is placed in the first group of the periodic table. Hydrogen like halogens (\[n{s^2}n{p^5}\]) is deficient by one electron to the respective noble gas configuration, helium (\[1{s^2}\]). Hydrogen, hence, has a similarity to alkali metals and halogens.
