Description: There are two ways to determine the charge on the Nitrate ion (NO3 -). The first, and probably quickest is to just memorize that the Nitrate ion has a charge of 1- . [Note that the - sign goes after the number for ions.] The second way is to calculate the formal charge for the ion. While this is effective, it is time consuming. For this reason it is a good idea to understand how to find the charge of the Nitrate ion but then memorize that it is 1-. ----- Helpful Videos ----- Memorizing the Polyatomic Ions: youtu.be/vepxhM_bZqk Formal Charge Practice Video: youtu.be/-9f4H0puVzc Finding the Charge on Ion: youtu.be/N4N1Njh7nCo Introduction to Writing Electron Configurations: youtu.be/J-v9_ieCqJI How to Draw Lewis Structures: youtu.be/1ZlnzyHahvo Finding Valence Electrons (element): youtu.be/x1gdfkvkPTk Note that when we look at the charge on ions, it is important to understand that ions come in pairs. In an ionic compound like CsCl, the Cs is a positive ion (Cs+) and has transferred/lost an electron to the Chlorine atom which now has an extra electron and is negative (Cl-). We can dissolve CsCl in water and it will split apart into Cs+ and Cl-. The electron from the Cs is now with the Cl. For more help with chemistry visit Breslyn.org
