How Many Electrons In Hydrogen – Http://www..phy.nau.edu/~lavery/Mypage/Astrostuff/A150WEB1998/main2.html#startnotes Gases can have complex emission and absorption lines that tell us more about their conditions. Spectra of emission and absorption lines emitted by atoms (and molecules). Atoms consist of nuclei consisting of protons and neutrons and electrons around them. Hydrogen (1 proton) and helium (2 protons) are the lightest; There are atoms with up to 100 protons (G. Riecke number) giving 100 elements. Electrons in an atom are held by an electric potential proportional to 1/r2 as gravity. This force attracts positive and negative electric charges, but repels like charges – twice positive or twice negative. The protons in the nucleus of an atom are held together by the “strong force”, which is stronger than electricity but operates over very short distances. Electrons can only exist in certain energy levels of an atom because the two-dimensional wave particle means that they interfere with themselves in other levels. This behavior is described in a branch of physics called “quantum mechanics”. (photographed by G. Rieke). Electronic transitions between energy levels result in the absorption or emission of photons of a certain energy corresponding to the energy level difference. If an electron moves from the outer, higher energy to the inner, lower energy, energy is released in the form of photons. The properties of this photon depend on the energy difference between the orbits: Energy = Eorbit 1 – Eorbit 2 = h = hc / If a photon of the right energy “hits” an atom, it can be absorbed and cause an electron to jump outward with a higher energy. When the electron falls back into its original orbit, the same energy picture emerges. When atoms collide, electrons can be raised to outer orbits. When the electron returns to its original orbit, a photon of characteristic energy is emitted. In astronomical conditions, we can see emission lines or absorption lines in the spectrum depending on the relationship between the source and the entrained gases (animation by G. Rieke). The specific wavelengths absorbed by the atoms in the gas are canceled out by the light that reaches us. Emission lines are created when photons are emitted from a gas thin enough to be transparent and continuous. Absorption and emission spectra: (from R. J. Lavery, http://www..phy.nau.edu/~lavery/Mypage/Astrostuff/A150WEB1998/main2.html#startnotes) html#startnotes) If more energy is given to the electron, it can leave the positive charge behind the atom. Since the electron no longer transitions between two specific energy states, the atom can absorb different energies in that state. Electrons of different energies can be captured by a positive nucleus, producing photons of different energies. Although it is convenient to picture protons, neutrons, and electrons as tiny dots, quantum mechanics says that they are not exactly detectable and actually resemble tiny clouds of fog. We cannot predict exactly what they will do, which leads to a scientific conflict with the philosophy of determinism: science shows that there is a fundamental uncertainty about what will happen in the future at the highest wavelengths) At high temperatures, most electrons are in high-energy orbits, or they have completely escaped from the atom, which causes them to emit special lines that are not only associated with high temperatures. 2) Composition analysis. Since each element (as well as each type of molecule) has allowed orbits for its electrons and therefore has its own shape of spectral lines, spectra can be used to determine what an element is made of (here are some examples by A. Larson, http://www.astro.washington.edu/astro101v)
Spectra can be thought of as a “cosmic barcode” indicating the position of the object (Frauenhofer Solar Spectrum, from R. Fosbury, http://www.stecf.org/~rfosbury/home/photography/Eclipse99/csp_description.html) 3) Motion Indicators. By understanding the Doppler effect, we can use spectra to measure the speed of a distant object. In the case of electromagnetic radiation: At the point of emission “blue shift” ==> mirror lines become shorter wavelengths and at longer distances it emits “red”. Also, it “leaves” the waves emitted from the left, changing the light to red. (From the University of Saskatchewan,

(Japan Aerospace Exploration Agency, JAXA, http://spaceinfo.jaxa.jp/note/shikumi/e/shi10_e.html.) Although the entire spectrum changes, changes in spectral lines are easy to detect because their wavelengths are unique. The Doppler effect is equal to the speed of the object as a cycle of the frequency speed (or wave), where c = speed of light and the Greek capital delta (triangle) represents the change – that is, the cycle of the wave divided by the original wave is equal to the speed of the source divided by the speed of light.

Hydrogen (H), a colorless, odorless, tasteless, flammable gas, is the lightest member of the chemical elements. A hydrogen atom has a nucleus containing a proton containing one unit of positive charge; The electron, which carries one unit of negative charge, is also associated with this nucleus. Under normal conditions, hydrogen gas is a free mixture of hydrogen molecules, each of which contains two atoms, a diatomic molecule, H.

Although hydrogen is the most abundant element in the universe (three times more abundant than helium, which is the next most abundant element), it makes up only 0.14 percent of the Earth’s crust by weight. However, it is found in large quantities as part of ocean water, glaciers, rivers, lakes, and the atmosphere. As part of countless carbon compounds, hydrogen is present in all animal and plant cells and in oil. Although it is often said that more carbon compounds are known than other elements, since hydrogen is present in almost all carbon compounds and also forms many compounds with all other elements (except some noble gases), hydrogen compounds may be more numerous.
Primary hydrogen finds its main use in the ammonia production industry (a combination of hydrogen and nitrogen, NH).
There are three known isotopes of hydrogen. The mass isotopes of hydrogen are 1, 2, and 3, with the most common isotope 1 known as hydrogen (symbol H or
H) but also known as protium. An isotope of mass 2 (symbol D or
H) is an isotope with one proton and two neutrons in each nucleus and contains 10.
