WebWHEN ATOMIC RADIUS DECREASES (ACROSS A PERIOD LEFT TO RIGHT)-Electrons have stronger pull from the nucleus, therefore ionization energy is HIGH-Electron affinity is HIGH because there is little shielding from electrons - the nucleic pull is stronger-Electronegativity is HIGH because the above 2 points are HIGH Bond Spectrum Difference in … 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 − ... WebThe reduction of the EA of the first member can be attributed to the small size of the n = 2 shell and the resulting large electron–electron repulsions. For example, chlorine, with an EA value of –348 kJ/mol, has the highest value of any element in the periodic table. The EA of fluorine is –322 kJ/mol. shenzhen honor electronic co. ltd products

WebAug 10, 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. Some generalizations can be made about the electron affinities of certain groups in the periodic table. WebPart 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. Since A is on the right side of B, therefore its electron affinity is higher than B

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 ...
