Greater electron affinity
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. WebApr 4, 2024 · The three factors affecting the electron affinity of a molecule are Nuclear Charge, Atomic Size, and Electronic Configuration. Nuclear Charge: The greater the …

Web119 rows · Electron affinity can be defined in two equivalent ways. First, as the energy … WebSep 29, 2014 · K has a more exothermic electron affinity because the electron gained fills the 4s orbital. In Ca the electron goes to 3d. The energy gap between 4s and 3d is enough to make the process barely exothermic. Note that the numbers given in tables are positive but that the process is exothermic.

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. The electron affinities of the noble gases have not been conclusively measured, s… WebMar 2, 2024 · 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 − → X − + energy Another way to define …
WebNov 26, 2024 · Superhalogens are molecules that have electron affinities (EA) greater than that of Cl, the element with the highest EA (3.62 eV). It is well known that noble gases have closed electronic shell structure and hence have high ionization potentials and low electron affinities, due to which they are chemically inert and resistant to salt formation ...

WebNov 20, 2024 · Electron affinity can be either positive or negative value. The greater the negative value, the more stable the anion is. Although affinity varies greatly across the periodic table, some patterns emerge. Generally, the elements on the right side of the periodic table will have large negative electron affinity.
WebThe electron affinity of an atom or molecule is the propensity for that particle to gain an electron. This is an exothermic process for all non-noble gas elements. There are general trends in electron affinity across and down the periodic table of elements. chiropractor mcneese st lake charles laWebIt takes less energy to remove the first electron compared with the second because it is in a higher energy level than the second electron.
