WebElectron gain enthalpy is the energy produced when a neutral isolated gaseous atom receives an extra electron to form the gaseous negative ion or anion. It can be represented by ∆egH. ... Although there is a slight difference between the two, electron gain enthalpy is sometimes also referred to as electron affinity. The amount of energy ... WebFeb 22, 2024 · Therefore, electron gain enthalpy is a negative value, while electron affinity is a positive value. Basically, both terms represent the same chemical process. The electron gain enthalpy gives us an idea about how strong an electron is bound to an atom. Greater the amount of energy released, greater the electron gain enthalpy. The value …

Increasing order of electron gain enthalpy of group 16 is:

The electron affinity (Eea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion. X(g) + e → X (g) + energy This is not the same as the enthalpy change of electron capture ionization, which is defined as negative when energy is released. In other words, the enthalpy change and the electron affinity … WebMay 19, 2016 · But the electron configuration is $3s^1$ and consequently, can also gain an electron and become the more stable $3s^2$ state. It's more likely that a sodium atom will lose an electron, and become a cation, but the electron affinity reflects the modest gain in stability as $3s^2$ after attaching an extra electron. helsinki oppilaitokset
