Comparing Chemical Formulas of Hydrogen Compounds
On the comparison of the chemical formulas of hydrides
The principle of the chemical formulas of substances that you want to understand is the main way to compare the chemical formulas of hydrides. Hydrogen, the basis of elements, is combined with various elements, and the chemical formulas of the compounds formed have their own characteristics. After analyzing and comparing, the rules of combination can be obtained.
Look at the number of atoms in the combination of elements and hydride, and the ratio of the number of atoms varies according to the properties of the elements. For example, when halogen elements, the genera of chlorine, bromine, and iodine, are combined with hydride, each atom of halogen is combined with one atom of hydrogen to form the formula of HCl, HBr, and HI. The number of electrons in the outermost layer of this Guine halogen element is seven. To achieve the stable structure of the octet, only one electron is needed, and the hydrogen atom can provide one electron, and the two combine in a ratio of one.
Looking at the oxygen group elements again, oxygen and hydrogenation combine into water, and the chemical formula is H2O O. Sulfur and hydrogenation combine to form H2O S. The reason for this is that the number of electrons in the outermost layer of oxygen and sulfur is six, and two electrons are required to achieve stability, so they combine with dihydrogen atoms.
Nitrogen group elements, taking nitrogen as an example, combine with hydrogenation to form ammonia, and the chemical formula is NH. The number of electrons in the outermost layer of nitrogen is five, and three electrons are required to achieve stability, so they can combine with three hydrogen atoms.
From this perspective, the chemical formulas of compounds formed by the combination of different elements and hydrogen are determined by the electronic structure of the element itself. In order to achieve a stable structure, each element combines with hydrogen atoms in a specific ratio according to its outer electron requirements, resulting in different chemical formulas. By comparing the chemical formulas of hydrides, the nature of the chemical combination of elements can be explored, and the law of chemical change can be understood, which is of great benefit to the research of chemistry.
