Is Hydrogen an Alkali Metal
On whether hydrogen is an alkali metal
Hydrogen is the first of the elements. Its unique nature, existing in the world, often gas-like, light and colorless and odorless. Looking at the genus of elements, the alkali metal family has a common nature. If hydrogen can be classified as an alkali metal, it is necessary to examine the characteristics of the two in detail.
For alkali metals, in the atomic structure, the outermost layer is only one electron, which is loosely bound and easy to get rid of the constraints of atoms, so it shows strong reductivity. In chemical reactions, it often actively loses electrons and turns into cations. And its elemental texture is soft, its melting point and boiling point are low, and its chemical properties are very active. It responds to hydrogen and alkali when it encounters water.
The atom of hydrogen has only one outer electron, and in this regard, it seems to be similar to alkali metals. However, the behavior of hydrogen is very different. Although hydrogen can lose electrons to form cations, it often loses electrons to anions, which is very different from alkali metals that lose electrons blindly. For example, in sodium hydride, hydrogen gains electrons with negative monovalence. And the elemental substance of hydrogen, the norm is diatomic molecular hydrogen, and the chemical activity is significantly different from that of alkali metals. Alkali metals react violently in contact with water, and hydrogen and water need specific conditions to react. Furthermore, the melting point and boiling point of hydrogen are extremely low. Although it seems to be similar to the low melting boiling point of alkali metals, the essential causes are different. Hydrogen is maintained by weak intermolecular forces, while alkali metals are interacted by metal bonds.
To sum up, although hydrogen has an alkali metal-like electronic structure, its chemical behavior and physical properties are unique and cannot be simply described as alkali metals. Hydrogen has its own identity in the forest of elements, and its nature is complex. The way of research still needs to be deeply investigated before it can be understood.
