Ionised hydrogen molecule
WebHII regions are emission nebulae created when young, massive stars ionise nearby gas clouds with high-energy UV radiation. They are composed primarily of hydrogen, hence the name (astronomers use the term HII to refer to ionised hydrogen, HI for neutral hydrogen), and have temperatures of around 10,000 Kelvin.They can extend over … WebAtomic hydrogen is the basic fuel required for star formation in a galaxy. When hot ionised gas from the surrounding medium of a galaxy falls onto the universe, the gas cools and forms atomic hydrogen. This then becomes molecular hydrogen and eventually leads to the formation of stars.

Web21 nov. 2024 · In a fully ionized hydrogen plasma, both `H` ions (protons) and electrons contribute to pressure but since the mass of electron is quite small `(=m_(P)//1836)`, only protons contribute to mass density. Thus ... =` molecular weight of … WebIonised hydrogen, commonly called HII (pronounced H-two), is a hydrogen atom that has lost its electron and is now positively charged. It is easily detected at optical wavelengths …
Webionised hydrogen molecule possesses nine degrees of freedom, and so nine co-ordinates are necessary to specify its configuration. These may be taken as the co … Web26 apr. 1999 · If a hydrogen atom absorbs a photon with wavelength less than 912Å the atom is ionized with the "extra" energy going into the kinetic energy of the electron. Collisions between electrons "thermalize" this energy heating the nebular gas to a temperature of about 10,000K.
WebAn ion (/ ˈ aɪ. ɒ n,-ən /) is an atom or molecule with a net electrical charge.The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention.The net charge of an ion is not zero because its total number of electrons is unequal to its total number of … Web16 jan. 2024 · Water molecules consist of two hydrogen atoms and one oxygen atom, but some assert that infusing water with additional hydrogen produces benefits that plain water cannot deliver.
