30 Οκτ 2024 · Hydrogen, a colorless, odorless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. The earliest known chemical property of hydrogen is that it burns with oxygen to form water; indeed, the name hydrogen is derived from Greek words meaning ‘maker of water.’.
Hydrogen is a chemical element; it has symbol H and atomic number 1. 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.
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral hydrogen atom contains a nucleus of a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. [1]
Describe the hydrogen atom in terms of wave function, probability density, total energy, and orbital angular momentum. Identify the physical significance of each of the quantum numbers (n, l, m) of the hydrogen atom. Distinguish between the Bohr and Schrödinger models of the atom.
Most hydrogen is produced by heating natural gas with steam to form syngas (a mixture of hydrogen and carbon monoxide). The syngas is separated to give hydrogen. Hydrogen can also be produced by the electrolysis of water.
Delve into the comprehensive guide on Hydrogen, the universe's most abundant element. Uncover its rich history, physical and extended chemical properties, and myriad uses in industries, medical applications, and emerging technologies.
The hydrogen atom wavefunctions, \(\psi (r, \theta , \phi )\), are called atomic orbitals. An atomic orbital is a function that describes one electron in an atom.
