Great effort! Your answer is close, but the correct definition of electronegativity is the tendency for an atom to pull electron density toward itself. It is a measure of the ability of an atom to attract electrons in a chemical bond. Electronegativity is an important concept in understanding chemical bonding, as it helps determine the polarity of a bond. The greater the electronegativity difference between two atoms, the more polar the bond between them. To determine the electronegativity of an atom, you can refer to the electronegativity chart, such as the Pauling scale, which assigns values to each element.
