The electron affinity of argon, like all noble gases, is 0, or very close to it, due to its chemical inertness.
Among the elements listed: Highest electron affinity: Cl (Chlorine) with an electron affinity of -349 kJ/mol. Lowest electron affinity: Ar (Argon) with an electron affinity of 0 kJ/mol (inerts gases like Ar typically have low electron affinities).
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.
Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.
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.
The electron affinity of sulfur is -200 kJ/mol.
Among the elements listed: Highest electron affinity: Cl (Chlorine) with an electron affinity of -349 kJ/mol. Lowest electron affinity: Ar (Argon) with an electron affinity of 0 kJ/mol (inerts gases like Ar typically have low electron affinities).
Electron affinity is the energy released when an electron is added to a neutral atom. Elements with a zero electron affinity value include neon, helium, and argon because they have stable electron configurations and do not readily accept additional electrons.
Helium has no electron affinity.
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.
Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion.

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.
Yes, that is part of the definition of electron affinity.
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
The electron affinity of sulfur is -200 kJ/mol.
Chlorine has a negative second electron affinity because it releases energy when gaining an additional electron. This makes it less likely to accept a second electron compared to its first electron affinity, which is positive.
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
