Passage

DIRECTIONS: Read the passage given below and answer the questions that follows:

The tendency of an atom to attract shared pair of electrons towards itself is called electronegativity. both have tendency to attract electrons but electron affinity is for isolated atoms. Whereas electronegativity is for bonded atoms.

A polar covalent or ionic bond of depending on their tendency to attract bonded electron.

There is no unit of electronegativity as is tendency of a bonded atom not an energy
