Electron affinity: period trend (video) Khan Academy

The electron affinity of molecules is a complicated function of their electronic structure. For instance the electron affinity for benzene is negative, as is that of naphthalene, while those of anthracene, phenanthrene and pyrene are positive. In silico experiments show that the electron affinity of hexacyanobenzene surpasses that of fullerene. WebAssalam O Alikum!

WebWhat is Electron Affinity? The energy released when an electron is added to a neutral atom to produce a negatively charged ion is called electron affinity. Only a few chemical elements, mostly halogens, have measured electron affinities. WebAn element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay.
