In this video, the speaker explains how covalent bonds work, with a focus on how polar covalent bonds form between atoms. They use the example of water to explain how two hydrogen atoms can share electrons with one oxygen atom, and how this creates a dipole electric field.

• 00:00:00 In this video, we will review the covalent bond. This bond is split into the polar covalent bond and the nonpolar covalent bond. We'll start with the nonpolar covalent bond, also known as the a polar or biancovalent bond. This chemical bond forms when two nonmetals unite. These nonmetals can be equal or have a difference of electro negativity. This bond is characterized by the fact that electrons are shared equally between the atoms and this happens thanks to the small difference of electro negativity. Therefore, if the atoms that form a molecule are the same, the electrons are shared equitably between the two. For example, two hydrogen atoms can form a simple covalent bond while two oxygen atoms can form a covalent nonpolar double bond. Finally, two nitrogen atoms can form a covalent nonpolar triple bond. In this case, you can recognize that each union yields a dipole electric field. The molecule of water is a polar covalent bond because in this case two chemical bonds each hold together one hydrogen atom and one oxygen atom. Each of these unions holds two electrons, so we have a total of four electrons. In contrast, the polar coval
• 00:05:00 In this video, the name of an accepted molecule, such as ammonia, is explained in terms of polar covalent bonds between nitrogen and three hydrogen atoms. Since nitrogen has five electrons in its valence shell, it can join with other atoms to form covalent bonds. In this case, the three hydrogen atoms each have one electron valence, and the nitrogen has two extra electrons that are not shared with another atom. This nitrogen can contribute those two electrons to form a fourth covalent bond, and so on. This fourth bond is in equilibrium with the first three, since each atom has one electron that is not shared. This fourth bond forms when nitrogen joins with a proton, and so we have a coordination bond. You may have enjoyed the video and would like to leave a like, so please do.
