Difference Between Electronegativity And Electron Affinity

 

6 Differences Between Electronegativity And Electron Affinity

The main difference between electronegativity and electron affinity is the type of chemical interaction that they measure.

S.NO.	Electro-negativity	Electron Affinity
1.	Electronegativity measures the ability of an atom to attract electrons in a chemical bond.	Electron affinity measures the energy change that occurs when an atom gains an electron.
2.	Electronegativity is a measure of an atom's ability to pull the shared electrons in a chemical bond toward itself.	Electron affinity is a measure of an atom's tendency to accept an electron.
3.	Electronegativity is typically measured on a scale from 0 to 4, with higher values indicating a higher ability to attract electrons.	Electron affinity is typically measured in units of energy, such as joules or electron volts.
4.	Electronegativity is influenced by the atomic number, the size of the atom, and the shielding effect of the outer electrons.	Electron affinity is influenced by the size and charge of the atom.
5.	Electronegativity is used to predict the type of chemical bond that will form between two atoms.	Electron affinity is used to predict the stability of an atom or ion.
6.	Electronegativity is a property of an atom.	Electron affinity is a property of an atom or ion.
