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.
