Electron-gain enthalpy
WebThe electron gain enthalpy describes the enthalpy change when the atom gains an electron (again, this atom is in special conditions, such as in the gaseous state and in the ground state). This reaction results in the formation of an anion. The reaction can occur as follows: First gain enthalpy of electrons. S(g) + e- → S- (g) Second gain ...

The giant planets Jupiter and Saturn consist mostly of hydrogen. However, due to its light nature, it is much less abundant (0.15% by mass) in the earth’s atmosphere. Of course, in the combined form
WebJun 1, 2015 · The energy of an electron in vacuum (isolation from the nucleus) is zero (because it cannot feel the nucleus' attractive pull). But when it occupies a definite energy level in the atom, the energy of the system reduces. The extra energy is then released, which is why you find that the electron gain is generally exothermic.
