Nomenclature
- ==ionic nomenclature== * ^^metal^^ (1A, 2A, Al+3, Zn+2, Cd+2, Ag+1) and ^^nonmetal^^
1. write metal name * is it a transition metal? (NO) 2. write non-metal name * ending changes to -ide * ^^metal^^ (1A, 2A, Al+3, Zn+2, Cd+2, Ag+1) and ^^polyatomic ion^^
1. write metal name * is it a transition metal? (NO) 2. write polyatomic ion name * DO NOT CHANGE NAME * ^^transition metals, Sn, Pb^^ and ^^nonmetal^^
1. write transition metal name 2. use roman numeral to indicate charge on transition metal * +1 (I) * +2 (II) * +3 (III) * +4 (IV) 3. write nonmetal name with -ide ending
- ==covalent nomenclature== * ^^two nonmetals^^ together
1. write first nonmetal name - non change 2. write second nonmetal name with -ide ending 3. use prefix to indicate numbers of atoms of each non metal * prefixes
1. mono- *not used for first nonmetal - ex. NO → Nitrogen Monoxide 2. di- 3. tri- 4. tetra- 5. penta- 6. hexa- 7. hepta- 8. octa- 9. nona- 10. deca- * “oo” drop first o -- ex. NO → Nitrogen Mon(o)oxide * “ao” drop a
- ==acid nomenclature== * chemical formula begins with H+ * based on anion (second part, H2SO3) * ends in -ide → hydro-root name of ion-ic acid * ex. HCl → hydrochloric acid * ends in -ite → root name of ion-ous acid * ex. HClO2 → chlorous acid * ends in -ate → root name of ion-ic acid * ex. HClO3 → chloric acid
- questions * is there a metal? * yes - is it a transition metal * no - no parentheses * yes - (roman numerals) * no - prefix-first, prefix-last-ide * does the formula begin with H+? * yes - acid, follow through based on anion
