Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
Hydrogen compounds are compounds containing the element hydrogen. In these compounds, hydrogen can form in the +1 and -1 oxidation states. Hydrogen can form compounds both ionically and in covalent substances. It is a part of many organic compounds such as hydrocarbons as well as water and other organic substances.
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite.
In the classic meaning, hydride refers to any compound hydrogen forms with other elements, ranging over groups 1–16 (the binary compounds of hydrogen). The following is a list of the nomenclature for the hydride derivatives of main group compounds according to this definition: [9] alkali and alkaline earth metals: metal hydride; boron: borane ...
Hydrogen bromide – HBr; Hydrogen chloride – HCl; Hydrogen cyanide – HCN; Hydrogen fluoride – HF; Hydrogen peroxide – H 2 O 2; Hydrogen selenide – H 2 Se; Hydrogen sulfide – H 2 S; Hydrogen telluride – H 2 Te; Hydroxylamine – NH 2 OH; Hypobromous acid – HBrO; Hypochlorous acid – HClO; Hypophosphorous acid – H 3 PO 2 ...
Hydrogen compounds are those chemical compounds which contain hydrogen. Subcategories. This category has the following 11 subcategories, out of 11 total. ...
Binary hydrogen compounds in group 1 are the ionic hydrides (also called saline hydrides) wherein hydrogen is bound electrostatically. Because hydrogen is located somewhat centrally in an electronegative sense, it is necessary for the counterion to be exceptionally electropositive for the hydride to possibly be accurately described as truly behaving ionic.
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral hydrogen atom contains a single positively charged proton in the nucleus, and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. [1]
