Question

What nature does hydrogen show?

Answer 1

Hint: The chemical element hydrogen has the symbol H and the atomic number $$1$$. Hydrogen is the lightest element in the periodic table, with an atomic weight of $$1.008$$. The most common chemical element in the universe is hydrogen.

Complete answer:
Since hydrogen has a single electron in its valence shell, it exhibits dual nature.
It can share its one electron with another metal or nonmetal product, such as alkali metals from Group $$1$$ of the periodic table, or it can obtain one electron to complete its valency of two, such as halogens from Group 17.
Since it only has one electron in its outer shell, hydrogen has a dual existence. This means that, like a normal halogen, a hydrogen atom can easily gain an electron to form a complete outer shell, or lose an electron to form an alkali metal. Since it already has two electrons in its outer shell, hydrogen can be diatomic, rendering it unreactive.
Hydrogen has a dual existence since it only has one electron in its K-shell, which is the outermost shell. As a result, it can either take or lend one electron (like halogens) (like alkali metals). As a result, it exhibits properties of both groups $$1$$ of the periodic table and group $$17$$ of halogens, and can be classified as belonging to both groups.
Hydrogen has the simplest electronic structure, consisting of just one electron. It loses one electron in group $$1$$ and gains one electron in group 17.

Note:
The study of the different natures that a matter possesses or exhibits is referred to as the dual nature of matter. As a result, matter is said to have dual nature, i.e., it has both particle and non-particle properties.
