Zinc Nitrate Properties and Bonding

The video explores whether zinc nitrate (Zn(NO3)2) is ionic or covalent. It concludes that the compound is ionic due to the presence of a metal (zinc) and non-metals (nitrogen and oxygen). Zinc, a transition metal, consistently has a 2+ charge, while the nitrate ion has a 1- charge. The ionic bond forms between the positively charged zinc ion and the negatively charged nitrate ions. However, within the nitrate ion, the bonds between nitrogen and oxygen are covalent, as they are between non-metals. Overall, the compound is ionic due to the interaction between the zinc and nitrate ions.
