Aim: Summary of naming ionic and molecular compounds  DO Now: 1. Name the following: a. NaOH b. Li 2 S c. MgH 2 (hint: H - is hydride ion) d. H 2 O e. K 3 N f. CaSO 4 2. Write formulae for the following: a. beryllium chloride b. copper (I) oxide (430 only) c. diphosphorus pentoxide d. aluminum carbonate e. ammonium phosphate f. sulfur dioxide

Ionic Compounds A. Ionic Compounds without transition metals apply following rules: 1. The metal ion's name does not change regardless of charge 2. The non-metal's name ends in “ide”. 3. When metals are bonded to polyatomic ions, which consist of two or more atoms with one overall charge, the same rules apply

Ionic Compounds Cont. B. Ionic Compounds with Transition Metals 1. we have to specify the charge of the transition metal ion by using a Roman numeral * Make sure in both cases (with and without a transition metal) the sum of the charges is equal to ZERO *

Molecular Compounds (Covalent Compounds)  we have a naming system that reveals the number of atoms involved. PrefixNumber of atoms mono1 di2 tri3 tetra4 penta5 hexa6
