Question

One end of a molecule has a positive charge and the other end of the same molecule has a negative charge. What is the best term to describe this molecule?

A) ion
B) dipole
C) isotope
D) electron

Answer 1

Answer: option B, dipole

Step-by-step explanation:

If there is a considerable change in Electronegativity between two atoms then opposite charges formed on the atoms

Atom with more Electronegativity gets negative charge and atom with less Electronegativity gets positive charge.

Example, CO2, Oxygen gets negative charge because of more Electronegativity and carbon gets positive charge due to less Electronegativity.

Answer 2

An ion is an element that bears only one electric charge, either positive or negative. An isotope is an element with the same number of protons but a different number of neutrons. An electron is a negatively charged subatomic particle. A dipole fits the characteristics. Hence, the answer is B.
