Vodonik (lat. Hydrogenium) je definisao Britanac Henri Kavendiš 1766. On nije prvi izolovao ovaj element, već je to uradio Paracelzus u 16. veku reakcijom metala i jake kiseline, i nazvao ga „zapaljivim vazduhom“. Kavendiš je formirao vodonik reakcijom cinka i hlorovodonične kiseline.
In Slavic mythology, vodyanoy (Russian: водяной, IPA: [vədʲɪˈnoj]; lit. ' [he] from the water' or 'watery') is a water spirit. In Czech and Slovak fairy tales, it is called vodník (or in Germanized form: Hastrman ), and it is considered to be the equivalent creature as the Wassermann or nix of German fairy tales.
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 H2, sometimes called dihydrogen, [11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2. In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
Vodnik ( Russian: Водник; Automotive number GAZ-3937 and its modified version GAZ-39371) is a Russian high-mobility multipurpose military vehicle manufactured by GAZ. It is a "heavy modification" of the civil GAZ-2330 "Tigr".
Vodik je kemijski element koji u periodnom sustavu elemenata nosi simbol H, atomski (redni) broj mu je 1, a atomska masa mu iznosi 1,00794 (7). Vodik nema određen položaj u periodnom sustavu. Ima jedan valentni elektron kao alkalijski metali, a od njih se razlikuje mnogo većom energijom ionizacije.
