Ionization energy equation in joules
Webjoule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds. In electrical terms, the joule equals one watt-second—i.e., the energy released in one … Web19 jun. 2024 · This means that in order to remove the electron from the ground state of a hydrogen atom in the gaseous state and create a hydrogen ion, you need to supply 2.181 ⋅ 10−18 J of energy. This means that for 1 atom of hydrogen in the gaseous state, you have. H(g) +2.181 ⋅ 10−18.J → H+ (g) + e−. Now, the ionization energy of hydrogen ...
