Re: Electron affinity
Electron affinity is the energy released when an electron is added to a neutral atom in the gaseous state. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Re: Electron affinity
does electron affinity and electronegativity have the same trends on the periodic table?

Re: Electron affinity
Electron affinity represents the energy spent or released when an electron is added to a gaseous molecule to create an ion. An example of this is the electron affinity of chlorine (-349 kJ mol-1) the negative sign represents a release in energy.
Electronegativity is the tendency of atoms to attract a bonding pair of electrons. For example, Florine is the most electronegative element on the periodic table beucase this element has 5 electrons is the 2p shell and the optimal electron configuration for this shell has six electrons. Fluorine is close to the ideal number of electrons therefore the nucleus tightly holds onto the electrons.
