The electron gain enthalpy of an element is a measure of the firmness or strength with which an extra electron is bound to it. It is measured in electron volts per atom or kJ per mole. It can be an endothermic or exothermic reaction when you add an electron to the atom.
Electron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom. During the addition of an electron, energy can either be released or absorbed.
Apr 5, 2024 · Electron gain enthalpy, in simple terms, describes the energy change that occurs when a neutral atom gains an electron to form a negative ion. It is a measure of how much energy is released or absorbed during this process.
3 days ago · The amount of energy released when an isolated gaseous atom takes an electron to create a monovalent gaseous anion is known as electron gain enthalpy. If an atom contains a spontaneous tendency, it means a positive tendency to gain an electron, then conventionally, its electron gain enthalpy is said to be negative.
The electron gain enthalpy of an atom is negative when energy is released on the addition of an electron. It can be used to estimate the stability of an atom as, more the negative value of enthalpy, the more stable the ion. It is often represented as ΔHeg and is measured in the unit of electron volts per atom or kJ per mole (kJ/mol).
Mar 23, 2024 · In this comprehensive chemistry tutorial designed for Class 11-12 students, dive deep into the concept of electron gain enthalpy. Understand its significance...
Apr 1, 2024 · Electron gain enthalpy is the energy change that occurs when a neutral isolated gaseous atom gains an extra electron to form a negative ion or anion. The electron gain enthalpy measures the strength with which an additional electron is bound to an atom and can be either exothermic or endothermic.
Feb 13, 2024 · The electron gain enthalpy is the release of energy when an extra electron is added to a neutral atom. On the other hand, electron affinity is the tendency of an element to add an electron to form an anion.
