Only 0.000053 percent of air is composed of hydrogen, making it the ninth most prevalent gas in the air. Nitrogen takes the lead, making up 78.084 percent of air, more than one million times more space than hydrogen. Oxygen also makes up a large part of air at 20.947 percent.Know More
Air is made up of many different gases including argon, which takes up about 0.93 percent of air. The concentration of carbon dioxide, the fourth most common gas in the air at 0.038 percent, is slowly increasing.
The amount of ozone is also increasing; although, it is still barely traceable from the ground. Ozone has a much higher concentration near the stratosphere, where it protects the Earth from harmful ultraviolet rays. The amount of water vapor in the air varies depending on location.Learn more in Atoms & Molecules
When a hydrogen molecule is attached to a carbon molecule on a benzene ring, the hydrogen is called a "benzylic hydrogen." The benzylic hydrogen is always attached to the carbon molecule on the side chain.Full Answer >
Henry Cavendish is credited with discovering hydrogen in 1766 in London, though alchemist Paracelsus in the 1500s and Robert Boyle in 1671 did preliminary work on the subject. However, Cavendish identified hydrogen gas as a discrete substance. In 1783 Antoine Lavoisier provided the name hydrogen, Greek for water former.Full Answer >
Hydrogen bonding is a force of attraction between a slightly positive hydrogen of one molecule to a slightly negative region of another molecule. An individual hydrogen bond is not very strong, but in large numbers, hydrogen bonds can represent a substantial force of attraction within a substance.Full Answer >
Hydrogen is the most abundant element in the universe and can be found in a wide variety of organic and inorganic compounds, including water and sugars, and in the mass of stars. Hydrogen is the most basic element in the periodic table and contains one proton and one electron.Full Answer >
