89724 Assertion: Electron affinity refers to an isolated atom's attraction for an additional electron while electronegativity is the ability of an atom of an element to attract electrons towards itself in a shared pair of electrons.
Reason: Electron affinity is a relative number and electronegativity is experimentally measurable.
