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.

水素(すいそ、英: hydrogen、羅: hydrogenium、仏: hydrogène、独: Wasserstoff)は、原子番号1の元素である。元素記号はH。原子量は1.00794。非金属元素のひとつである。 ただし、一般的に「水素」と言う場合、元素としての水素の他にも水素の単体である水素分子(水素ガス)H2、1個の陽子を含む原子核と1個の電子からなる水素原子、水素の原子核(ふつう1個の陽子、プロトン)などに言及している可能性があるため、文脈に基づいて判断する必要がある。
