Electronegativity, electron affinity, and ionization energy are used to predict whether two atoms will bond and what kind of bond it will be. Match the correct definition to each term. The energy absorbed or released when a neutral atom loses one electron:

Electronegativity- is the ability of an atom in a compound to attract the bonding pair of electrons closer to itself.

electron affinity- the energy released when an atom accepts electrons to form a negative ion.

ionization energy - The energy absorbed or released when a neutral atom loses one electron:

Explanation:

If two atoms X-Y constitute a bond, the dash in between the two atoms indicate a shared pair of electrons. If peradventure, Y has a greater ability to attract the electron pair towards itself compared to X making the electron pair to be closer to the nucleus of Y compared to X, we define this property of Y as electro negativity.

Consider an atom X that accepts one mole of electrons to form one mole if negative ion as shown below;

X(g) + e ---> X^- (g)

The energy released by this process in which X accepts an electron and forms a univalent negative ion is known as electron affinity.

Similar, when X looses an electron to form a positive ion, the energy released or absorbed during this process is known as ionization energy.

X(g) >X^+(g) + e
