## Total Energy in One Hydrogen Atom

[caption id="attachment_14456" align="alignright" width="440"] Hydrogen Bomb[/caption] Hydrogen is the lightest of the elements. However, there are three isotopes of hydrogen. The lightest of these is protium. It contains just one proton and one electron. Let’s determine the total energy of one protium atom. Its mass is 1.007822 atomic mass units. So what is the total energy one hydrogen atom produces if obliterated? By obliterated, we mean 100% conversion from matter to energy, not the mere energy of separation of particles, as in fission. Einstein’s Mass-to-Energy Equation In our calculating, it is important we stick to proper units. If we were cooking and the recipe called for a cup of flour, would we substitute a tablespoon? Our equation is Einstein’s mass to energy expression, E = mc² If the mass is…
