OverviewAI-generated

Hydrogen is a chemical element with the symbol H and atomic number 1. It is classified as an atmophile element, a nonmetal, an s-block element, and a reducing agent. The element has an oxidation state of -1, 1, or 0 and an electronegativity of 2.2. Its antiparticle is antihydrogen.

The substance was discovered in 1766 by Henry Cavendish, Mikhail Lomonosov, and Antoine Lavoisier in the Russian Empire, the United Kingdom, and France. It is part of period 1 and group 1, and is a component of water. Physical properties include a mass of 1.008, a density of 0.089870, a refractive index of 1.000132, a speed of sound of 1270, and a thermal conductivity of 0.1805.

Waterstof is een chemisch element met symbool H (La: Hydrogenium) en atoomnummer 1. Het element komt als zodanig niet in geïsoleerde vorm voor in normale omstandigheden, maar vormt door de hoge reactiviteit verbindingen. Onder atmosferische omstandigheden vormt waterstof een twee-atomig molecuul: diwaterstof, dat meestal gewoon als waterstof of waterstofgas aangeduid wordt. Waterstof is het meest voorkomende element in het universum. Het normale isotoop van waterstof "protium" bestaat maar uit één proton en één elektron en bevat dus geen neutronen. Losse atomen waterstof worden ook wel "in statu nascendi" genoemd.
