Would you expect nonmetals to have larger electron affinities than metals?
Yes. Non metals have larger electron affinity than metals as non metals accept electrons more easily than metals.
Why the value of electron affinity is positive for noble gases?
The electron affinity of noble gases is positive because they are already stable with a complete valence electron shell. Adding an extra electron would force them to become less stable, requiring energy input, which results in a positive electron affinity value.
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.
What is energy released on adding an electron to an isolated gas phase atom?
The energy released on adding an electron to an isolated gas phase atom is called electron affinity. It represents the willingness of an atom to accept an additional electron. The process can release energy if the atom's electron affinity is negative, indicating that the atom is stable after gaining an electron.
which element would have a greater affinity for an additional electron Be or O?

What element has the most negative electron affinity Al Si S Cl?
Chlorine (Cl) has the most negative electron affinity among these elements. It has a higher tendency to gain an electron to form a chloride ion compared to aluminum (Al), silicon (Si), and sulfur (S).

This strong attraction allows fluorine to readily accept an additional electron and achieve a stable electron configuration.
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 energy released on adding an electron to an isolated gas phase atom?
The energy released on adding an electron to an isolated gas phase atom is called electron affinity. It represents the willingness of an atom to accept an additional electron. The process can release energy if the atom's electron affinity is negative, indicating that the atom is stable after gaining an electron.
Why electron affinity of dinegative ion is endothermic?
When an electron is added to a dinegative ion, it is already in a very stabilized state due to the presence of two extra electrons. Adding another electron would result in electron-electron repulsions and destabilize the system, requiring energy input. This leads to an endothermic process for adding an electron to a dinegative ion.
How do you determine electron affinity?
Electron affinity is determined by measuring the energy released when an atom in the gas phase gains an electron to form a negative ion. A higher electron affinity indicates that an atom has a greater ability to attract and hold onto an additional electron. This can be influenced by factors such as the atomic size, effective nuclear charge, and electron configuration of the atom.
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.

Why is electron affinity expressed as a negative number while the ionization energy has a positive number in calculating the energy of ion pair formation?
when dealing with atomic chemistry in most cases a negative number indicate the gaining of at least one electron and a positive number indicate the loss of an electron. the definition of electron affinity in a nutshell is the ENERGY required to add an electron to in most cases the outermost shell, so the more electron you trying to add the higher the nergy and the more negative the number would be which would represent the amount of electron added eg.. if i want to add let say 2e- to a oxygen atom then the result would be O(g) + 2e- = O2-(g) also you can see that an anion is formed. on the other hand ionization energy is the somewhat the opposite, it is the removal of the most loosely held electron from a atom in the GASEOUS state forming cation in the end. eg.. Na(g) = Na+(g) + e- . Note that while ionization MUST be in the GASEOUS state electron affinity not necessarily have to. So dont used both terms as positive or negative loosely like that its just an indication of telling us what is going on whether the atom is loosing or gaining electron/s. hope this helps .
Which has lower electron affinity between oxygen and fluorine?
Fluorine has a lower electron affinity than oxygen. This is because fluorine already has a full outer shell of electrons and adding another electron would create repulsion due to electron-electron interactions. Oxygen, on the other hand, has space in its outer shell to accept an additional electron more easily.
