Hydrogen

The chemical element hydrogen is represented by the letter h and atomic number 1, additionally is the lightest element in the element table. Under mundane circumstances, hydrogen is a gas composed of diatomic molecules with the formula h2. It is prodigiously flammable, achromic, insipid, odourless, and non-toxic. In the macrocosm, hydrogen is the most prevalent chemical since it makes up around 75% of all commonplace stuff. Plasma hydrogen makes up the majority of stars like the sun. The majority of the hydrogen that subsists on earth is found in molecules like dihydrogen monoxide and organic compounds. Each atom of hydrogen's most mundane isotope, 1h, has one proton, one electron, and no neutrons. except when under prodigiously high pressures, hydrogen is nonmetallic. It seldom makes more than one covalent bond with nonmetallic elements, giving ascend to molecules like dihydrogen monoxide and proximately all organic compounds. Since protons are typically exchanged between soluble molecules in acid-base reactions, hydrogen plays a categorically paramount part in these processes. In ionic compounds, hydrogen can subsist as a positively charged (i. e. , cation) species designated by the symbol h+ as a supposititious succedaneum a negatively charged (i. e. , anion) species kenned as a hydride.
