Ionization energy and electronegativity

Postby Hadji Yono-Cruz 2L » Sat Nov 03, 2018 1:38 am

Since both ionization energy and electronegativity are the energies to remove an electron, then what is the difference between them? Does ionization energy refer only to ionic bonds and electronegativity refers to covalent bonds?

Both of them follow the same trend on the periodic table: both increase as you go across from left to right and decrease as you go top to bottom.

However, they differ since ionization energy is the energy required to remove an electron from a neutral atom in its gaseous state whereas electronegativity is the ability of an atom in a molecule to draw bonding electrons to itself.
