It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
Under ordinary conditions, hydrogen gas is a loose aggregation of hydrogen molecules, each consisting of a pair of atoms, a diatomic molecule, H 2. The earliest known important chemical property of hydrogen is that it burns with oxygen to form water, H 2 O; indeed, the name hydrogen is derived from Greek words meaning “maker of water.”
Hydrogen is a colorless, odorless and tasteless gas that is the most abundant element in the known universe. It is also the lightest (in terms of atomic mass) and the simplest, having only one proton and one electron (and no neutrons in its most common isotope).
Water molecules are made up of two elements - hydrogen (white atoms) and oxygen (red atoms). Water has a specific ratio of two hydrogen atoms to one oxygen atom.
12 lip 2023 · Hydrogen can form compounds that contain a proton (H +), a hydride ion (H −), an electron-pair bond to H, a hydrogen bond, or a three-center bond (or electron-deficient bond), in which two electrons are shared between three atoms. Hydrogen gas can be generated by reacting an active metal with dilute acid, reacting Al or Zn with a strong base ...
Liquid hydrogen is used in the study of superconductors and, when combined with liquid oxygen, makes an excellent rocket fuel. Hydrogen combines with other elements to form numerous compounds. Some of the common ones are: water (H 2 O), ammonia (NH 3 ), methane (CH 4 ), table sugar (C 12 H 22 O 11 ), hydrogen peroxide (H 2 O 2 ) and ...
