Introduction to Hydrogen
Hydrogen is a chemical element having chemical symbol H and atomic number 1. It has the average atomic weight of 1.00794 u (1.007825 u for hydrogen-1) and is the lightest element. Hydrogen in its monatomic form (H1) is the highly abundant chemical substance, which includes around 75% of the Universe's baryonic mass. Non-remnant stars are usually comprises of hydrogen in its plasma state.
At standard pressure and temperature, hydrogen is a tasteless, colorless, non-toxic, odorless, nonmetallic, highly combustible diatomic gas with the molecular formula "H2". Naturally occurring atomic hydrogen is uncommon on Earth because hydrogen readily forms covalent compounds with various elements and is present in the water molecule and in most organic compounds. Hydrogen plays a significant role in acid-base chemistry with various reactions exchanging protons among soluble molecules.
Properties
Combustion:
Hydrogen gas is extremely flammable and will burn in air at a highly broad range of concentrations between 4% and 75% by volume. The enthalpy of the combustion for hydrogen comes out to be -286 kJ/mol:
2 H2(g) + O2(g) → 2 H2O(l) + 572 kJ (286 kJ/mol)
Electron energy levels
The energy levels of hydrogen can be computed fairly accurate by using the Bohr model of the atom, which conceptualizes the electron as like the "orbiting" the proton in similarity to the Earth's orbit of the Sun. Although, the electromagnetic force attracts electrons and protons to each other whereas the planets and celestial objects are attracted to one other through gravity. Because of the discretization of angular momentum postulated in early quantum mechanics given by Bohr, electron in the Bohr model can only take some allowed distances from the proton and thus only some allowed energies.
