Jan 28, 2016 · The more energy is released when this happens, the more positive the electron affinity. As far as chlorine and bromine are concerned, your teacher is actually wrong. Chlorine does have a higher electron affinity than bromine. So, why does that happen? As you know, both chlorine and bromine are located in group 17 of the periodic table, which ...

Oct 30, 2015 · This means that when adding an electron to an atom releases energy, electron affinity will actually be listed as a positive value. #E_"a" = -DeltaE# When electron affinity is negative, it implies that adding an electron to an atom actually requires energy. So if you go by the sign convention, the electron affinity of bromine is actually ...

Electron affinity is the attraction a neutral atom has for a non-bonding electron. Moving from left to right and bottom to top on the period table, electron affinity increases. This is because going from left to right and bottom to top, the atomic radius decreases so it is easier for the nucleus to attract negative electrons.

Jun 9, 2024 · Electron affinity is that energy released when one electron is added to a gaseous atom of an element. For Mg ... , 2006), the electron affinity of Bromine is -325 kJ/mol. Hope this helps.

Jun 17, 2024 · Iodine has a higher electron affinity than bromine. This is because iodine is a larger atom with more electron shielding, making it more stable and less likely to repel an additional electron ...

May 23, 2024 · The irregularity in the electron affinity trend between Cl and F is due to the small size of the F atom. Although F definitely has a higher attraction for an electron than Cl (as evidenced by its ...

Jan 10, 2018 · The ionization energy for potassium is 419 kJ/mol. The electron affinity for bromine is -325 kJ/mol. Use these values and Hess's law to calculate the change in enthalpy for the following reaction per mole of reagent:

Fluorine has a greater electron affinity than bromine. This is because fluorine is the most electronegative element, meaning it has a stronger attraction for electrons compared to bromine.

Dec 5, 2016 · See the explanation. Ionization energy is the energy required to remove a valence electron from an atom or ion in its gaseous state, causing it to gain a positive charge as the electron is removed. "X" + "energy"rarr"X"^(+) + "e"^-" Fluorine is in period two of the periodic table, meaning that it contains electrons in only the first two energy levels at ground state. It …

Dec 7, 2015 · Sometimes it is; especially for elements to the right of the Periodic Table. Electron affinity is the enthalpy associated with the reaction: M(g) + e^(-) rarr M^(-)(g) We would expect this enthalpy to increase across a Period from left to right (because of the increased nuclear charge), and to decrease down a Group, as the nuclear charge is insulated by intervening electron …
