Is an element with a large negative electron affinity most likely to form a positive ion a negative ion or a neutral atom?
negative ion
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?
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).
Which element group have the most negative electron affinities?
Fluorine flourine is the most electronegative element
Why the electron affinity of fluorine is less than that of chlorine?

Which element group have the most negative electron affinities?
Fluorine flourine is the most electronegative element
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.

What is chemical affinity?
I'm quite sure what is being referred to here is "electron affinity". Electron affinity is a routine college freshman chemistry concept. So, out of a textbook: "The energy that accompanies the addition of an electron to a gaseous atom to form an anion" An anion is a negatively charged ion. The most electro-negative element, fluorine, releases the most energy when it reacts with an electron. Fluorine, like oxygen, nitrogen and most gases (except the "inert" or "noble" gases) are DI-atomic. So fluorine is F2 (the 2 should be a subscript). But this reaction assumes mono-atomic fluorine (also called "nascent"). The the reaction is: F + e- ---> F- And this releases 328 kilo-joules of heat per mole.
Who can help me with this problem Rank the following elements by electron affinity from most positive to most negative I have the elements Ar Cl O Sb and Rb?
The order is: O, Cl, Sb, Rb, Ar.
