A step-by-step explanation of how to draw the O2 Lewis Dot Structure (Oxygen Gas (Diatomic Oxygen). For the O2 structure use the periodic table to find the total number of valence electrons for the O2 molecule. Once we know how many valence electrons there are in O2 we can distribute them around the central atom with the goal of filling the outer shells of each atom. In the Lewis structure of O2 structure there are a total of 12 valence electrons. O2 is also called Oxygen Gas (Diatomic Oxygen). In order to make sure the outer shell of the Oxygen atoms are full you will need to form a double bond in this Lewis structure. By doing so each of the Oxygen atom in the Lewis structure for O2 will have octets. ----- Steps to Write Lewis Structure for compounds like O2 ----- 1. Find the total valence electrons for the O2 molecule. 2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside. 3. Put two electrons between atoms to form a chemical bond. 4. Complete octets on outside atoms. 5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds. ----- Lewis Resources ----- • Lewis Structures Made Simple: https://youtu.be/1ZlnzyHahvo • More practice: https://youtu.be/DQclmBeIKTc • Counting Valence Electrons: https://youtu.be/VBp7mKdcrDk • Calculating Formal Charge: https://youtu.be/vOFAPlq4y_k • Exceptions to the Octet Rule: https://youtu.be/Dkj-SMBLQzM Lewis Structures are important to learn because they help us understand how atoms and electrons are arranged in a molecule, such as Oxygen Gas (Diatomic Oxygen). This can help us determine the molecular geometry, how the molecule might react with other molecules, and some of the physical properties of the molecule (like boiling point and surface tension).
