How do you know which element has the highest electron affinity?
Since this electron is farther away, it should be less attracted to the nucleus and release less energy when added. However, this trend applies only to Group-1 atoms. Electron affinity follows the trend of electronegativity: fluorine (F) has a higher electron affinity than oxygen (O), and so on.
Which element has second highest electron affinity?
Therefore, chlorine has a higher electron affinity than fluorine, and this orbital structure causes it to have the highest electron affinity of all of the elements.
What is difference between electronegativity and electron affinity?
Electronegativity is defined as a chemical property which decides the propensity of an atom to attract an electron. Electron affinity is defined as the amount of energy liberated when a molecule or neutral atom acquires an electron from outside.
What does it mean to have a high electron affinity?
The electron affinity is the energy change when an atom gains electrons. The convention is that the higher or more positive the electron affinity value, the more readily the atom accepts an electron.
Why does fluorine have less electron affinity than chlorine?
Electron affinity of fluorine is less than that of chlorine. This is due to the reason explained below: Fluorine has seven electrons in 2p-subshell whereas chlorine has seven electrons in its 3p-subshell. Therefore, repulsion among the electrons will be more in the 2p-shell of fluorine than 3p-subshell in chlorine.
What is the relationship between electron affinity and atomic radius Why does this occur?
Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.
Which would least strongly attract electrons from other atoms in a compound?
The elements of group 1 are the ones which would least strongly attract electrons from other atoms in a compound.
