The periodic property that is used to determine whether a covalent molecule is polar or not is
A.
atomic radius
B.
ionization energy
C.
electron affinity
D.
electronegativity
Correct answer is D
The periodic property that is used to determine whether a covalent molecule is polar or not is electronegativity.
Electronegativity is a measure of the ability of an atom to attract electrons in a chemical bond. The greater the electronegativity of an atom, the more strongly it will attract electrons.
