KEY TERMS: reverse cross over rule, metal, non-metal

3.02 - Naming Ionic Compounds - 5:48

KEY TERMS: balance both sides of the equation by placing a number (coefficient) in front of the compound. Don't be afraid to have to change that number if it does not completely balance the equation. Balance polyatomic ions first. Remember that REACTANTS are to the left of the arrow and PRODUCTS are to the right of the arrow. Refer to episode on "Counting Atoms". Don't forget your diatomic molecules:oxygen = O2hydrogen = H2bromine = Br2chlorine = Cl2iodine = I2fluorine = F2nitrogen = N2

KEY CONCEPTS: When naming Binary Acids, start by identifying the hydrogen atom as "hydro" and name the non-metal using the "ic" ending and add the word acid.Rules for Oxy-Acids:They are derivatives of polyatomic ions and polyatomic variations. Follow the following 4 rules:i.) _ate ions become _ic acidii.) per_ate ions become per_ic acidsiii.) __ite ions become _ous acidsiv.) hypo__ite ions become hypo_____ous acidsBases contain hydroxide ion (OH)-1**NOTE: NO "hydro" for oxy-acids
