What is the Difference between Electronegativity Electron Affinity Ionization Energy
Electronegativity, Electron Affinity and Ionization Energy are the names of some scientific terms that are frequently used in science subjects and have wide industrial applications. Being related to energy utilization and production, people feel much confusion about the difference between these terms. To resolve this issue, here is the complete description of these scientific terms along with the key differences between them.
Electronegativity
Electronegativity is the propensity of an atom in a molecule to attract the electrons of other atom, belong to any other molecule, towards itself to make a covalent bond. This is atomic number and the distance of atoms that affects the electronagtivity of an atom.
Electron Affinity
Electron affinity is the term that describe the amount of released energy during formation of a negative ion or the amount of energy that release during the addition of an electron in fully neutralized atom or molecule.
Ionization Energy
To remove I mole of an electron from 1 mole of atoms or ions, the required energy is called ionization energy. The strange fact about ionization energy is that, in case of small molecules, the required energy for removing electrons i.e. ionization energy is higher and vice versa.
Electronegativity vs Electron Affinity vs Ionization Energy
Electronegativity, Electron Affinity and Ionization Energy are different scientific terms in many respects. Electronegativity is the somewhat different from other two terms, because it the tendency of an atom to attract other atoms rather than the required or released amount of energy during transfer of electrons. However, electron affinity is the energy required to transfer the electron in an already neutral atom or molecule and ultimately making it a negative ion. This is just opposite to that energy that is required to take out electron from an atom or ion and is called ionization energy.
