Electron affinity is a property of an isolated atom in the gaseous state. It is defined as the amount of energy released when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion It is an energy term and is measured in units of joules per mole.
Electronegativity is a property of an atom in a molecule. It is a chemical property that says how well an atom can attract electrons towards itself. It can be expressed only in arbitrary dimensionless units with respect to a reference atom.
Which of the following statements about electronegativity is false?
(a) Electronegativity is the ability of an atom in a molecule to attract electron density toward itself.
(b) Electronegativity is the same thing as electron affinity.
(c) The numerical values for electronegativity have no units.
(d) Fluorine is the most electronegative element.
(e) Cesium is the least electronegative element.
