Electron affinity is the energy released when an atom gains an electron to form a negative ion, while electron gain enthalpy is the enthalpy change accompanying the addition of an electron to a gaseous atom. Electron affinity is a specific term used in the context of forming an ion, while electron gain enthalpy is a general term for the enthalpy change associated with gaining an electron.

Is the electron affinity of germanium high or low?
The electron affinity of germanium is considered to be moderate. Germanium is a metalloid element with an electron affinity that falls between that of metals and nonmetals.
What value of different electron affinity will give you an ionic bond?
An ionic bond forms when there is a large difference in electron affinity between two atoms. Typically, one atom has a high electron affinity (strongly attracts electrons) and the other atom has a low electron affinity (weakly attracts electrons), leading to the transfer of electrons from one atom to the other to form charged ions that are held together by electrostatic forces.
What are the trends and exceptions to the trends in electron affinity?
One trend in electron affinity is that it generally increases across a period from left to right on the periodic table due to increasing nuclear charge. However, there are exceptions such as the decrease in electron affinity between groups 2 and 13 as a result of increased electron repulsion. Additionally, noble gases have very low or zero electron affinities, contrary to the trend of increasing affinity.
How is Hf related to the H of a reaction?
The Hreaction is the difference between Hf, products and Hf, reactants
Why does chlorine have more electron affinity than fluorine although it is below fluorine in periodic table?
Chlorine has more electron affinity than fluorine because of its larger size, which allows for better electron-electron repulsion. This means that when an electron is added to a chlorine atom, it is not as strongly attracted as it would be in a smaller fluorine atom. This results in a higher electron affinity for chlorine.

What is the difference between electron negativity and electrons affinity?
ok, so electron affinity is the amount of energy given off when a particular atom excepts electrons. Essentially, it is the likelihood that an atom will accept an electron, while ionization energy is how much energy is needed to take an electron off of a particular atom
Why would flurine have the highest electron affinity?
Fluorine has the highest electron affinity because it has a small atomic size and high effective nuclear charge, which results in a strong attraction between the nucleus and incoming electrons. This strong attraction allows fluorine to readily accept an additional electron and achieve a stable electron configuration.
Is there a correlation of electron affinities to atomic radii?
The relation between electron affinity and atomic radius is inversely proportional.

What is the basic difference between electron affinity and electro negativity?
Electron affinity is the energy released when an atom gains an electron, indicating its ability to attract and hold onto electrons. Electronegativity, on the other hand, is a measure of an atom's ability to attract electrons in a chemical bond, affecting the overall polarity of the bond. In essence, electron affinity refers to the individual atom's attraction to electrons, while electronegativity pertains to how an atom behaves in a chemical bond.
Why does chlorine have more electron affinity than fluorine although it is below fluorine in periodic table?
Chlorine has more electron affinity than fluorine because of its larger size, which allows for better electron-electron repulsion. This means that when an electron is added to a chlorine atom, it is not as strongly attracted as it would be in a smaller fluorine atom. This results in a higher electron affinity for chlorine.
Who has higher electron affinity between bromine and Iodine?
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 compared to bromine.
Which element would most likely have a positive electron affinity between Na Al Rb and Ar?
Chlorine (Cl) would most likely have a positive electron affinity. Typically, elements with high electron affinities are found on the right side of the periodic table, closer to the noble gases. Among the choices given, Argon (Ar) is a noble gas and has a positive electron affinity.
