Period 2 electron affinity
WebApr 11, 2024 · Thus, decreasing order of electron affinity of given elements is, Sulphur > Oxygen > Carbon > Nitrogen. So, out of the given elements to us, nitrogen has the lowest electron affinity. Hence, the correct option is (A) Nitrogen. Note: As the atomic size decreases from left to right across the period and increases down the group electron … WebCl (g) + e⁻ → Cl⁻ (g); EA = -349 kJ/mol. The negative sign shows that the process releases energy. Adding an electron to a metal requires energy. Metals are much more likely to …
Period 2 electron affinity
Did you know?
WebMar 2, 2024 · Updated on March 02, 2024. Electron affinity reflects the ability of an atom to accept an electron. 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 − ... WebElectronegativity is a derived quantity, so it is not directly measurable. It is just a calculation done on some other values. It is relative to hydrogen which was assigned a value of 2.20 on the Pauling scale. There are other electronegativity scales than …
WebThere are two types of electron affinity, first and second. The first involves the addition of an electron to a neutral atom. Because this exothermic process releases energy, first electron affinities are negative values. The second pertains to the addition of an electron to a …
WebElectron affinity (the energy associated with forming an anion) is more favorable (exothermic) when electrons are placed into lower energy orbitals, closer to the nucleus. … WebNov 3, 2024 · Within a period, Carbon has a lower electron affinity than nitrogen, because nitrogen already has half-full p-subshell (which is more stable). A notable exception to the trend with regards to it increasing up a group is Flourine (period 2) which has a lower electron affinity than chlorine (period 3) due to a higher magnitude of electron ...
