1 eV is 1.6x10-19 Joules.
So, 1 Joule is 1 / 1.6x10-19 eV
One more electron.
Ambot
It is the atom of deuterium. Its nucleus is composed of a proton and one neutron. The atom has one electron that is orbiting around the nucleus.
Oh, dude, you're talking about defibrillation, right? Well, technically, around 200 to 1000 volts can stop a heart, but don't go around shocking people thinking you're a superhero. Leave that to the professionals, like seriously.
The electron configuration of magnesium is 1s2 2s2 2p6 3s2. Mg+ has one less electron (electrons have negative charge, so a positive charge is a lack of electrons) so you remove one from the outermost orbital: 1s2 2s2 2p6 3s1, or simply [Ne] 3s1.
1 volt = 1 joule per coulomb 3 joules x 1 coulomb = 3 volts
Each fission of U235 releases 200 Mev (200 million electron volts) which in terms of Joules is 3.2 x 10-11 Joules
One million electron volts (1 MeV) is equal to the amount of energy gained by an electron when accelerated through a potential difference of one million volts. This unit is commonly used in particle physics to express the energy of particles.
MeV stands for "million electronvolts." It is a unit of energy commonly used in nuclear and particle physics to measure the energy of particles. One electronvolt is the amount of kinetic energy gained by an electron when accelerated through an electric potential difference of one volt.
The two are not compatible units. An Electron Volt is the amount of charge one electron gains or loses when it crosses an electrical potential difference of 1 volt.
Each fission of Uranium 235 releases about 200 MEV (million electron volts), which is 3.2 x 10-11 Joules (1 electron volt = 1.6 x 10-19 joules). That does not sound much, but there a lot of fissions per second in a reactor.
There is no relationship between eV and V. An electron/volt is the energy acquired by an electron as it moves through an electric field of one volt. So 110 KeV is the energy acquired by an electron as it moves through an electric field of 110,000 volts.
One kWh has 2.25 x 1025 eV. (The electron-volt is a very small unit, used in particle physics.)
The amount of energy needed to move an electron from one energy level to another is known as the energy difference between the two levels. This energy difference is typically quantified in electron volts (eV) or joules.
They're different things. An "electron volt" is not the same as a "volt". An "electron volt" is an amount of energy. It's the work you have to do in order to lift one electron to a place that's 1 volt more negative, and also the amount of energy that one electron loses when it falls to a place that's 1 volt more positive. "1 joule" of energy is the amount of energy you pay for if you use 1 watt for 1 second, and that's about 6,250,000,000,000,000,000 electron volts of energy. If you use 1,000 watts for 1 hour, you pay for 1 kilowatt-hour of energy. That's about 22,500,000,000,000,000,000,000,000 electron volts of energy, or 3.6 million joules. It costs around 15¢ to 25¢ in most places. The "7 trillion electron volts" in the question is something like the amount of energy that you'd have to pay for if you used 1 watt for 0.00000112 second. It's not much.
There are 3.6 million joules in one kilowatt-hour (kWh).
The SI unit of energy is "Joules", although you could theoretically use "calories" or "Calories". However, usually due to the minute nature of atoms, I'm guessing that EV (electron volt being 1.6*10^-19 of a Joule) is more appropriate BTW, the basic unit of energy is Mass times distance squared over time squared.
