Hydrogen Valence Electrons
On the Valence Electron of Hydrogen
Hydrogen has unique characteristics among all elements. The number of its valence electrons is the key to exploring its chemical behavior.
Hydrogen has only one valence electron. This single valence electron, although rare, plays a most important role in chemical reactions. Because it has only one valence electron, hydrogen tends to lose or lose this electron in order to achieve a stable electronic configuration, similar to the inert gas configuration of helium; or it shares this electron with other atoms and forms a covalent bond.
When hydrogen combines with elements with strong electronegativity, such as oxidizing to form water, hydrogen tends to lose its valence electron and assume a positive monovalent state. At this time, the valence electron of hydrogen deviates from the hydrogen atom and is close to the more electronegative atom.
However, in many cases, hydrogen often bonds with other atoms by means of common electron pairs. In a hydrogen molecule, two hydrogen atoms each give their one valence electron to form a common electron pair, thus forming a stable covalent bond, and both achieve a relatively stable state by means of a common electron pair.
From this point of view, the single valence electron of hydrogen, although simple, makes hydrogen exhibit rich and variable properties in the field of chemistry, and plays an indispensable role in the formation of various compounds and the process of chemical reactions.
