Zinc Compounds and Naming Conventions

The video tutorial explains how to name the compound ZnBr2, which is a binary ionic compound consisting of a metal (zinc) and a non-metal (bromine). The naming process involves writing the metal's name followed by the non-metal with an 'ide' suffix, resulting in 'zinc bromide'. The video also discusses the covalent character of ZnBr2 and its IUPAC name. Additionally, it clarifies why zinc, despite being a transition metal, does not require a Roman numeral in its name due to its consistent +2 ionic charge.

What type of compound is ZnBr2?

• Binary ionic compound

• Covalent compound

• Metallic compound
