What else can I help you with?
Does high value of electron affinity for an atom means that it will gain electron easily?
Yes, that is part of the definition of electron affinity.
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
Does Sr have a high electron affinity or a low electron affinity?
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.
Halogen with the least-negative electron affinity?
The halogen with the least-negative electron affinity is astatine. Electron affinity and electronegativities decreases down a group. Since astatine is the last halogen located in Group 17 as you move down the column from fluorine, it has the least negative electron affinity.
Which has higher electron affinity fluorine or chlorine?
Fluorine has higher electron affinity than any other element.
Which has the lower electron affinity germanium or selenium?
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.
What is the second electron affinity of chlorine?
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.
How do you create an electron affinity reactor?
To create an electron affinity reactor you will have to use the second ionization energy.
What element has no electron affinity?
Helium has no electron affinity.
Why first electron affinity is greater than the second one?
The first electron affinity is generally greater than the second because the process of adding an electron to a neutral atom is typically more favorable than adding a second electron to an already negatively charged ion. When the first electron is added, it experiences relatively less repulsion from existing electrons. However, when a second electron is added, it encounters increased electron-electron repulsion due to the negative charge of the ion, making the process less exothermic and thus resulting in a lower electron affinity.
What is the second electron affinity positive or negative?
It is positive. In relation to oxygen at least.
What is an electron's electron affinity?
chloline
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.
Does high value of electron affinity for an atom means that it will gain electron easily?
Yes, that is part of the definition of electron affinity.
What is the electron affinity of sulfur?
The electron affinity of sulfur is -200 kJ/mol.

Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
