WebOct 11, 2024 · For example, the electron affinity of chlorine has the negative sign, which shows us the energy that is released to add one electron to an atom. The giving off of energy is shown with a negative sign. WebJan 30, 2024 · The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous -1 ions. It is the energy released (per mole of X) when this change happens. First electron affinities have negative values. …

WebElectron affinity measures the ease of gaining an electron by an atom. For example, the electron affinity of chlorine is −348.6 kJ/mol. The negative sign indicates that it is an exothermic change. Argon, however, has a positive electron affinity, indicating that formation of an argon anion requires energy to be supplied. WebExamples of electron affinity. Chlorine accepts the electron leases the 337 KJ / mole of energy. This is the first electron affinity. Oxygen atom accepts one electron to form O negative anion and related 141 kilo joule per mole of energy. This is first electron affinity. O-1 can accept one more electron to make over -2. It absorbs 880 KJ / mol ...
WebElectron affinity (EA) is defined as the change in energy (kJ/mole) of a neutral atom (in the gaseous phase) when one electron is added to it to create a negative ion. In other words, EA is the likelihood of a neutral atom acquiring an electron. ... For example, when a Group-17 atom gains an electron, it releases more energy than a Group-1 atom ... WebWhen two atoms form a chemical compound, the electron cloud is shifted towards the element with a higher electron affinity. When this difference is large enough, the electron is virtually transferred from one atom to the other creating an ionic bond. This is the case, for example, in the case of sodium-chlorine (Na-Cl) bonding in sodium chloride.
WebElectron Affinity Chemistry Questions with Solutions. Q-1: The process requires absorption of energy is. F→F –. Cl→Cl –. O – →O 2-. H→H –. Answer: c) O – →O 2-. Explanation: Addition of an electron to an isolated gaseous atom always releases energy,but adding electrons to an anion requires energy due to interelectronic ... 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 …
