1/4/2024 0 Comments Electron affinity![]() The electronegativities of other atoms are given a value considering their capabilities of attracting electrons.Įlectronegativity depends on the atomic number and the size of the atom in an element. This scale is called “ Pauling scale.” According to this scale, the highest electronegativity value that an atom can have is 4.0. This is a qualitative property of an atom, and in order to compare the electronegativities of atoms in each element, a scale where relative electronegativity values reside is used. Key Terms: Atom, Electron, Electron Affinity, Electronegativity, Endothermic Reaction, Exothermic Reaction, Pauling ScaleĮlectronegativity is the ability of an atom to attract electrons from outside. What is the Difference Between Electronegativity and Electron Affinity – Definition, Units of Measurement, Relationship with Atomic Numberģ. ![]() – Definition, Units of Measurement, Relationship with Atomic Number, Bonding The main difference between electronegativity and electron affinity is that electronegativity is the ability of an atom to attract electrons from outside whereas electron affinity is the amount of energy released when an atom gains an electron. Electronegativity and electron affinity are two terms that explain the behavior of elements due to the presence of electrons. However, electrons are very important in some chemical reactions because the exchange of electrons is the only difference between reactants and products in these reactions. Electrons are found everywhere since every matter is made up of atoms. Main Difference – Electronegativity vs Electron AffinityĪn electron is a subatomic particle of an atom.
