Di-Negative atoms are already electron rich in nature. This causes electron affinity is less. Since energy is needed to introduce another electron into the atom the process is endothermic.
The first electron affinity of magnesium is exothermic. This means that energy is released when a neutral magnesium atom gains an electron to form a magnesium ion.
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.
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.
chlorine has the highest electron affinity
An element with a large negative electron affinity is more likely to form a negative ion because it strongly attracts electrons to achieve a stable electron configuration. This results in the formation of negatively charged ions.
The first electron affinity of magnesium is exothermic. This means that energy is released when a neutral magnesium atom gains an electron to form a magnesium ion.
Yes. Electron affinity is the process by which a neutral atom gains an electron and the EA is the measure of energy released. The resulting ion will be negative.

chlorine has the highest 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
Sr has a relatively low electron affinity. Electron affinity is the energy change when an atom gains an electron to form a negative ion, and for strontium, this energy change is lower compared to other elements.
An element with a large negative electron affinity is more likely to form a negative ion because it strongly attracts electrons to achieve a stable electron configuration. This results in the formation of negatively charged ions.
The energy needed to remove an electron from a negative ion to form a neutral atom or molecule is called the electron affinity. It represents the energy change when an electron is added to a neutral atom or molecule to form a negative ion. The higher the electron affinity, the greater the energy needed to remove an electron.
Xenon's electron affinity refers to the energy released when a neutral xenon atom gains an electron to form a xenide ion. Xenon's electron affinity is low compared to many other elements, meaning it is less likely to gain an electron and form negative ions.
The electron affinity for phosphorus is -72 kJ/mol. This value represents the energy released when an electron is added to a neutral phosphorus atom to form a negatively charged ion.
Francium has the lowest electron affinity among all the elements because it is highly reactive and readily loses an electron to form a positive ion. This means that francium has a very low tendency to gain an electron.
