WebAug 14, 2024 · For larger atoms, the most loosely bound electron is located farther from the nucleus and so is easier to remove. Thus, as size (atomic radius) increases, the ionization energy should decrease. WebNov 26, 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Oxygen in the gas phase, for example, gives off energy when it gains an electron to form an ion of Oxygen. O + e – → O – – ∆H = Affinity = 141 kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity.

"WebSep 17, 2016 · Why does chlorine have a higher electron affinity than fluorine? To quote this answer: Fluorine, though higher than chlorine in the periodic table, has a very small atomic size. This makes the fluoride anion so formed unstable (highly reactive) due to a very high charge/mass ratio. Also, fluorine has no d-orbitals, which limits its atomic size. " - Greater electron affinity

Part 2: Electron affinity:-It is the amount of energy released when an electron is added to the neutral atom in its gaseous state to form an anion. Electron affinity increases across a period from left to right and decreased on going down the group.

Although Eea varies greatly across the periodic table, some patterns emerge. Generally, nonmetals have more positive Eea than metals. Atoms whose anions are more stable than neutral atoms have a greater Eea. Chlorine most strongly attracts extra electrons; neon most weakly attracts an extra electron.
