Hydrogen Metal or Nonmetal
The debate on whether hydrogen is a metal or a non-metal
There are many opinions on hydrogen in the world. Is it a metal or a non-metal? This is the key question of chemistry.
Or hydrogen is a non-metal. Looking at its normal state, hydrogen is a colorless and odorless gas, light in weight, and can float in the air. In chemical reactions, hydrogen often shows non-metallic properties. If it combines with oxidation to form water ($H ² O $), hydrogen gains electrons and becomes negative in the process. Is this atypical non-metallic state? And its chemical properties are active, and it often reacts with other substances.
However, there are also people who hold hydrogen as a metal. When hydrogen is under extremely high pressure, the state of its electron cloud changes greatly, and it can exhibit conductivity similar to that of a metal. Theoretically, it is speculated that the internal structure of hydrogen at this time, electrons can move freely, just like the electron sea model of metals, which proves that hydrogen has the characteristics of metals under special conditions.
From the periodic table of elements, hydrogen is ranked first and belongs to the alkali metal group. Its outer layer has only one electron, which is similar to alkali metals, but its properties are very different from alkali metals. Although hydrogen can lose electrons and have a positive valence, it is very different from the degree of difficulty of losing electrons in alkali metals.
Overall, the properties of hydrogen cannot be simply generalized with conventional metals or non-metals. Under normal conditions, it is mostly non-metallic; and under special conditions such as extreme high pressure, it can also appear as a metal. Therefore, whether hydrogen is a metal or a non-metal depends on the conditions and environment, and cannot be generalized.
