Each mole contains 6.023 x 10 23 molecules (Avogadro’s number). If the obliteration of a single atom of hydrogen doesn’t sound like it results in much energy, consider how much one single mole of hydrogen atoms contains. The energy for the complete conversion of one hydrogen atom isĮ = 1.504 x 10⁻ 10 joules Realizing the Enormity of It All We can also find the mass of a hydrogen atom using below method. Mass of 1 atom of hydrogen Mass of 1 proton1.67× 10-24g. Hydrogen has the lowest atomic mass and lowest atomic number. Calculations – Total Energy One Hydrogen Atom A Hydrogen atom is a neutral atom, as it contains one positively charged proton and a one negatively charged electron.

The velocity or speed of light in meters per second = 2.998 x 10 8. Therefore one protium atom has a mass in kilograms of,ġ.0078 x 1.66 x 10⁻ 27 = 1.673 x 10⁻ 27 kilograms Correct option is A) As H atom has one proton only, so the m ass of one H atom 1.66×10 24gm. Preparing for the Mathīut the hydrogen atom has a mass of 1.0078 a.m.u. If the mass is in atomic mass units, then energy must be in joules and the velocity of light meters per second. 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, The hydrogen atom consists of a proton of mass m p 1.7♁0-27 kg and charge q e 1.6♁0-19 C and an electron of mass m e 9.1♁0-31 kg and charge -q e.

In our calculating, it is important we stick to proper units. So what is the total energy one hydrogen atom produces if obliterated?īy obliterated, we mean 100% conversion from matter to energy, not the mere energy of separation of particles, as in fission. Let’s determine the total energy of one protium atom. It contains just one proton and one electron. However, there are three isotopes of hydrogen.
