Respuesta :
Answer: B. the atoms have an unequal sharing of the electrons
Explanation:
Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.
A polar moleucle is defined as a molecule which is formed when there is a difference of electronegativities between the atoms which leads to unequal sharing of electrons. example: [tex]HF[/tex]
Non-polar covalent molecule is defined as a molecule which is formed when there is no difference of electronegativities between the atoms which leads to equal sharing of electrons.Example: [tex]H_2[/tex]
Ionic bond is formed when there is complete transfer of electron from a highly electropositive metal to a highly electronegative non metal resulting into a neutral compound. Example; [tex]NaCl[/tex]
