One MeV is one megaelectron volts or one million electron volts, and the MeV is a measure of energy. It is equal to 1.60217646 × 10-13 joules.
one MeV has 1,000,000 eVs So one eV has 0.000001 MeVs
Muons decay by various methods, primarily, due to the weak interaction, into an electron and two neutrinos. The mass of the muon is 105.7 MeV/c2, with the mass of the electron being 0.511 MeV/c2, and the mass of the neutrino is less than 2.2 eV/c2. As a result, the loss of mass from muon decay, which is carried away as energy, is around 105.2 MeV/c2.
This is one of those things where the answer depends on what you mean. The fusion of a deuterium atom and a tritium atom into a helium atom produces about 14.1 million electron volts (MeV). By comparison, the fission of a uranium atom produces about 202 MeV, making a fission event over 14 times as powerful as a fusion event. But we could looked at it another way. A uranium-238 atom as an atomic mass of about 238, and the 202 MeV come from that mass, providing a yield of about 0.82 MeV per unit mass. By contrast, the 14.1 MeV from one deuterium, with an atomic mass of about 2, and one tritium, with an atomic mass of about 3, so the yield is about 2.8 MeV per unit mass, which makes fusion over 3 times as powerful as fission per mass per event.

200 MeV is a tiny quantity, it may sound a lot but is actually about 3 x 10-11 Joules. The point is that in a large fission reactor there are billions of fissions occurring every second and each one releases 200 MeV. As 1 Joule = 1 Watt.sec, and 1 KWh = 3.6 x 106 Watt.secs, you can see that the question is rather unbalanced!
None. Hydrogen and Helium are base elements.Helium is helium.Chemically yes, but with Nuclear Physics in stars:H + H --> D + e+ + v + 0.42 MeV, H + H --> D + e+ + v + 0.42 MeV, D + D --> He3 + n + 3.27 MeV (50%)H + H --> D + e+ + v + 0.42 MeV, H + H --> D + e+ + v + 0.42 MeV, D + D --> He3 + H + 4.03 MeV (50%)H + H --> D + e+ + v + 0.42 MeV, H + D --> He3 + gamma photon + 5.49 MeV, H + H --> D + e+ + v + 0.42 MeV, H + D --> He3 + gamma photon + 5.49 MeV, He3 + He3 --> He + H + H + 12.86 MeV (100%)H + D --> He3 + gamma photon + 5.49 MeV (100%)D + D --> He3 + n + 3.27 MeV (50%)D + D --> He3 + H + 4.03 MeV (50%)D + T --> He + n + 17.59 MeV (100%)T + T --> He + n + n + 11.33 MeV (100%)Four or two, depending on the kind of hydrogen isotope you are burning. As you can see in the equations above burning four ordinary atoms of hydrogen to ordinary helium is a complicated and slow process compared to burning two atoms of various isotopes of hydrogen, however a star has such tiny quantities of deuterium and tritium that depending on them for fusion helps little.

Cca. 200 MeV for 1 atom of uranium. (MeV = mega electronvolt = 106 eV).

The MeV means million electron volts. It's a measure of the energy the energy in the photon, which is a quantum (or specific quantity) of electromagnetic energy. This 1 megaelectron volt = 1.60217646 × 10-13 joules of energy.

Two hydrogen atoms fuse together to form one helium atom. During this process, tremendous amounts of energy are released, which is the source of energy in stars. This fusion reaction is known as nuclear fusion.
"Mrs" in Afrikaans is "Mev". "Mrs" (English) and "Mev" (Afrikaans) refers to a married woman. "Ms" (English) and "Mej" (Afrikaans) refers to a unmarried woman. "Mrs. Obama" would be "Mev. Obama" in Afrikaans. "Ms. Cyrus" would be "Mej. Cyrus" in Afrikaans.
Mevrou the abbreviation is Mev.
