Chemical Physical Atomic number: 1Atomic mass: 1Density: 0.088Melting point: -434.5Boiling point: -423.2 ColorlessTastelessOdorless Hydrogen was discovered by Henry Cavendish in 1776. Cavendish was the first to recognize that hydrogen was a gas discrete substance.and that it produces water when burned, a property which later gave it its name: in Greek, hydrogen means "water-former". BOHR MODEL Hydrogen gas was first artificially produced in the early 16th century, via the mixing of metals with acids. In 1766–81, Henry Cavendish was the first to recognize that hydrogen gas was a discrete substance. And that it produces water when burned, a property which later gave it its name: in Greek, hydrogen means "water-former." HISTORY OF HYDROGEN Hydrogen uses Henry Cavendish: who discovered hydrogen Hydrogen can easily evaporate into the atmosphere due to its lightness but it can be created by artificial means.hydrogen is being pointed out as a source for clean fuel. There are many benefits of using hydrogen instead of other sources of energy. It is widely used in many industries mainly because it causes for a more sustainable form of energy. If hydrogen is used as a fuel source, it will only need to be combined with oxygen, whose byproducts are only heat and water. double click to changethis text! Drag a cornerto scale proportionally. Fun facts for hydrogen 1. About 10 percent of the weight of living organisms is hydrogen – mainly in water, proteins and fats.2. Liquid hydrogen has the lowest density of any liquid.3. Solid, crystalline hydrogen has the lowest density of any crystalline solid.4. Hydrogen is the only element that can exist without neutrons. Hydrogen’s most abundant isotope has no neutrons.
