Find the energy of a hydrogen atom, whose electron is in the state n = 2. Use Avogadro's number to find the mass of a helium atom. What is the binding energy of 12C? The mass of an atom of 12C is 12 u (exactly), of an atom of 1H is 1.007825 u, and of a neutron is 1.008...
The electron's mass determined from the electronic g factor of 12 C 5+ is given by m e =0.0005485799092(4)u and has a three times lower error margin than the 1998 CODATA value. We elucidate the influence of the fine-structure constant and the binding energies of the electrons in 12 C...

Using the proton as origin, locate the center of mass of the proton–electron system in a hydrogen atom. Use the center-to-center distance r = 0.529 × 10-10 m, me = 9.11 × 10-31 kg, and mp = 1.67 × 10−27 kg. 6. Two point masses lie on the x-axis. Prove that the ce...

hydrogen atomproton-electron mass ratioIn this paper, we show the existence of an invariant minimum speed in space–time by forming the basis of a deformed special relativity so-called symmetrical special relativity (SSR). Such observer-independent minimum speed emerges from Dirac's large number ...
Ions may also be produced by removal of one or more electrons from a molecule usingelectron ionization(EI). This ionization method is historically the dominant ionization method used in MS (most commonly in gas chromatography–mass spectrometry [GC-MS] instruments) and is still used in some appl...
The mass of an electron is 0.000549 u. In kilograms, this mass is 9.1094 × 10−31. Since the neutral carbon atom has 6 electrons, the approximate mass of the nucleus is 1.992 648 × 10−26 −6 × (9.1094 × 10−31) = 1.992 101 × 10−26 kg. This calculation has not ...
There are only a few conceivable sources of graviton production, like black hole decay, spontaneous emission of gravitons from neutral hydrogen, bremsstrahlung from electron-electron collisions in stellar interiors, and conservations of photons to gravitons by interstellar magnetic fields. Here we will...
