Recognizing and writing What is different between ionic and covalent compound names and formulas? Ionic compounds have only one correct formula, so they have one way of being written. Covalent compounds can have several atomic arrangements.
Recognizing and writing What about acids? Acids are ionic bonds starting with hydrogen. Elemental form is hydro-____ acid. Polyatomic form is either _____-ic acid (-ate ion) or ______-ous acid (-ite ion).
Recognizing and writing What do you need to do when writing and naming compounds? 1. recognize the type 2. realize the different rules for each type 3. follow the rules for formulas and names
