This is (somewhat) like asking if it is better to be male or female. Reproduction requires both genders, and chemical reactions require elements of high electronegativity and elements of low electronegativity.

Which has the lower electron affinity germanium or selenium?
Selenium has the greater electron affinity
Why is the electron affinity of Mg lower than the electron affinity of K?
Generally, electron affinity increases (becomes less negative) in groups/families moving from top to bottom.
Why sulphur have higher negative electron affinity than oxygen?
Due to small size and high electron density of oxygen compared to sulphur, interelectronic repulsion is higher in oxygen, resulting in less energy being released when an electron is added to oxygen, due to lesser stability after electron is added, which is due to the interelectronic repulsion in the small oxygen atom. Hence electron affinity value is lower. It is an abnormality and exception to the general periodic trend of electronic affinity values.
Which has lower electron affinity between oxygen and fluorine?
This element is fluorine.
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).
Do Nonmetals with lower electron affinity have higher reactivity?
No. The most reactive non metal, fluorine, has the highest electron affinity.

How do you read the electrostatic series?
The electrostatic series ranks elements in order of their ability to gain or lose electrons. The list shows which elements have a higher affinity for electrons (indicating electron gain) and which have a lower affinity (indicating electron loss). This ranking can help predict the direction of electron transfer in chemical reactions.
Why does the oxidation of organic compounds by molecular oxygen to produce CO2 and water release free energy?
the covalent bonds in organic molecules are higher energy bonds than those in water and carbon dioxide.
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.

An electron absorbs a photon of light energy and becomes energized the electron shifts from?

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.
Is it better to have a higher IQ or a lower IQ?
A higher IQ reflects a higher intelligence than a lower IQ. So higher is better.
