Used to describe an atom's ability to chemically bond with another atom

"Electronegativity" is the atom's ability to chemically bond with another atom.

Explanation:

Electronegativity is the ability of the atom to attract the electrons towards another atom to it, these two atoms are associated through a bond. The phenomena is based on the atom's ionization energy and the electron affinity. The formation of the chemical bond takes place when the atoms share the electrons they have in outer shells. In other words we can say two atoms fuse together to form chemical bond.
