QUESTION 9

Electronegativity is a measure of an atom’s ability to
A. Attract the electrons in the bond between the atom and another atom
B. Repel the electrons in the bond between the atom and another atom
C. Attract the protons of another atom
D. Repel the protons of another atom

Respuesta :

Answer: A. Attract the electrons in the bond between the atom and another atom

Explanation:

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

The more electronegative an element is, the more is the tendency of the atom to attract the electrons in the bond between the atom and another atom

In a covalent bond of hydrogen and flourine in HF, flourine being more electronegative attracts the shared pair of electron towards itself and thus bears a partial negative charge and hydrogen being less electronegative cannot attract the shared pair of electron towards itself and thus being bears a partial positive charge.
