Hydrogen — This article is about the chemistry of hydrogen. For the physics of atomic hydrogen, see Hydrogen atom. For other meanings, see Hydrogen (disambiguation). ← hydrogen → helium … Wikipedia
Hydrogen embrittlement — (or hydrogen grooving) is the process by which various metals, most importantly high strength steel, become brittle and crack following exposure to hydrogen. Hydrogen cracking can pose an engineering problem especially in the context of a… … Wikipedia

Helium — otherusesHelium (He) is a colorless, odorless, tasteless, non toxic, inert monatomic chemical element that heads the noble gas group in the periodic table and whose atomic number is 2. Its boiling and melting points are the lowest among the… … Wikipedia
Helium flash — A helium flash is the runaway fusion of helium in the core of low mass stars of less than about 2.25 solar masses and greater than about 0.5 solar mass, or on the surface of an accreting white dwarf star. They may also occur in the outer layers… … Wikipedia
Hydrogen burning process — In the context of stellar nucleosynthesis, a hydrogen burning process can refer to either the proton proton chain reactions dominant in main sequence stars lighter than at most 5 solar masses, or to the CNO cycle dominant in heavier stars. Both… … Wikipedia
Liquid helium — Helium exists in liquid form only at very low temperatures. The boiling point and critical point depend on the isotope of the helium; see the table below for values. The density of liquid helium at its boiling point and 1 atm is approximately… … Wikipedia
CNO cycle — Overview of the CNO I Cycle. The CNO cycle (for carbon–nitrogen–oxygen) is one of two sets of fusion reactions by which stars convert hydrogen to helium, the other being the proton–proton chain. Unlike the proton–proton chain reaction, the CNO… … Wikipedia
proton-proton cycle — ▪ astronomy also called Proton proton Reaction, chain of thermonuclear reactions that is the chief source of the energy radiated by the Sun and other cool main sequence stars (star). Another sequence of thermonuclear reactions, called… … Universalium
