Hey, everyone. Let's take a look at this question together. A nonpolar covalent bond is what is it? Answer choice A when atoms are shared equally in a molecule, answer choice B when electrons are shared equally between two atoms, answer choice C a chemical bond where electrons are stationary or answer choice D none of the above. Let's work this problem out together to try to figure out which of the following answer choices best describes a nonpolar covalent bond. So in order to solve this question, we have to recall what it means when a bond is a nonpolar covalent bond. And we can recall that a nonpolar covalent bond is a bond that involves the equal sharing of electrons, meaning there is no dipole since those electrons are shared equally. So looking at our answer choices, which of the following answer choices best describes a nonpolar covalent bond. And we can see that answer choice B which says when electrons are shared equally between two atoms is the correct answer. Since a nonpolar covalent bond involves that equal sharing of the electrons between two atoms. And answer choices ac and D are all incorrect. I hope you found this video to be helpful. Thank you and goodbye.
