By losing two electrons, barium becomes cation and chlorine becomes anion, creating an ionic compound. Barium salts are extensively used in the industry. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Thus chlorine contains 6 lone pair and overall all compound is ionic. At the same time, the BaCl2 is a very different substance than Ba 2+ and Cl-.If you need to know how to balance chemical reactions, see my complete tutorial on balancing all types of chemical equations:Balancing Equations in 5 Easy Steps: https://youtu.be/zmdxMlb88FsMore Practice Balancing: https://youtu.be/Qci7hiBy7EQDrawing/writing done in InkScape. 2023 Feb 14;13(1):3. doi: 10.1186/s13395-023-00313-3.
