Naming and Writing Formulas for Type III Binary Compounds

This video tutorial by Mr. Millings covers Type 3 binary compounds, which consist of two nonmetals. It explains how these differ from Type 1 and 2 binary ionic compounds, which involve metals and nonmetals. The video provides detailed rules for naming Type 3 compounds using prefixes to indicate the number of atoms, followed by the suffix 'ide'. It also covers how to write chemical formulas from given names, emphasizing the order of elements based on electronegativity. The tutorial includes examples and practice problems to reinforce learning, concluding with a call to practice and self-assess understanding.
