Is an element with a large negative electron affinity most likely to form a positive ion a negative ion or a neutral atom?
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.
Which element group have the most negative electron affinities?
The halogens, specifically the group 17 elements, have the most negative electron affinities. This is because they have a strong attraction for gaining an electron to achieve a stable electron configuration with a full outer shell. Fluorine has the highest electron affinity among the halogens.
Which element would most likely have a positive electron affinity between Na Al Rb and Ar?
This element is rubidium.
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.
Why the electron affinity of fluorine is less than that of chlorine?
Generally electron affinity goes up as you go from left to right across the Periodic Table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine (note that the most electronegative element is fluorine however).The reason that the electron affinity is not as high as might otherwise be predicted for fluorine is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).Note that there are a number of other exceptions to the general rule of electron affinity increasing towards the upper right corner -- see the Related Questions links to the left for an explanation of some of those other exceptions.See also the Web Links to the left for more information about electron affinities and the fluorine-chlorine exception.

Which element would most likely have a positive electron affinity element Na element Al element Rb or elemnt Ar?
which of these is an extensive property of a substance? is it color, hardness, malleability, or volume
Do Nonmetals with lower electron affinity have higher reactivity?
No. The most reactive non metal, fluorine, has the highest electron affinity.

Which element group have the most positive electron affinities?
The group that has a substantial affinity for electrons is group 17, the halogens. These elements have 7 valence electrons which makes them have the highest affinity for electrons.
Which halogen has the lowest first ionization potential?
The outer electrons in bigger halogens are further from the nucleus and so they feel less attraction and so are easier to remove. Therefore, astatine has the lowest ionisation potential of the halogens.
Why is the electron affinity for clorine is greater than the electron affinity for iodine?
Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.The reason that the electron affinity is not as high as might otherwise be predicted for fluorine, is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).
What is chemical affinity?
Chemical affinity is the tendency of substances to react with each other to form chemical bonds. It is a measure of the likelihood that two substances will react to form a stable compound. Higher affinity means a stronger tendency to react.
