It is the energy change that occurs when an electron is added to a gaseous atom. Atoms with stronger effective nuclear charge have greater electron affinity. The reaction that occurs when an atom takes an electron may be represented as: X + e …
Periodic trends and Coulomb
WebPeriodic trends (such as electronegativity, electron affinity, atomic and ionic radii, and ionization energy) can be understood in terms of Coulomb's law, which is Fₑ = (q₁q₂)/r².For example, consider first ionization energy: Coulomb's law tells us that the greater the nuclear charge (q₁) and the shorter the distance between the nucleus and the outermost … WebIonization energy (IE): is a measure of the energy required to remove a valence electron from a gaseous atom.Mg (g) Mg + (g) + 1e-IE = 738 kJ/mol In general, atoms with low ionization energies do not bind their electrons very tightly and are very reactive.

WebThe electron affinity(Eea) of an atomor moleculeis 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 enthalpychange of electron capture ionization, which is defined as negative when energy is released. Web119 rows · Mar 23, 2024 · Electron affinity is the amount of energy … WebNov 14, 2024 · Here we can see that the second electron affinity is much higher than the first one.
