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.
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
The electron affinity of phosphorus can be represented by the process: P(g) + e- → P-(g). This equation shows the energy change associated with adding an electron to a phosphorus atom to form a phosphide ion.
The maximum electron affinity of P4 can be attributed to its molecular structure and the presence of empty p-orbitals that can accommodate an incoming electron. Phosphorus, in its elemental form, has a relatively high electron affinity due to its ability to stabilize the added electron through resonance and effective orbital overlap. Additionally, the molecular arrangement in P4 allows for optimal interactions between the added electron and the existing electron cloud, resulting in a more favorable energy state. This makes the addition of an electron to P4 energetically favorable, leading to its maximum electron affinity.
Helium has no 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 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
Yes, that is part of the definition of electron affinity.
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
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.
