|
|
|
Molecular elements |
Diatomic (hydrogen, nitrogen, oxygen, flourine, chlorine, bromine, iodine) Polyatomic molecules (P4, S8, Se8) |
|
|
|

|
|
|
Ionic compounds (writing formulas) |
1. Write the symbol for the metal cation and it's charge. 2. Write the symbol for the nonmetal anion and it's charge. 3. Cross over the subscript 4. Reduce the subscript to smallest whole number ratios. 5. Check the charges and make sure they cancel out |

|
Ionic compounds (formula to name) |
Cation: 1. Cation is first, most cations are monoatomic, Polyatomic ions Anion: 2. Has an ide ending 3. Write the cation and then the anion. If it's a Polyatomic ion, jst write it. |
|
|
|
Polyatomic ions (Naming) |
Metal + Polyatomic (ending is NOT changed to ide) ****Ionic and covalent bond**** Ex: Sodium Nitrate NaNO2 Copper (II) Sulfate CuSO4 |
|
|
|
Covalent Compounds |
**Nonmetal bonded to nonmetal** (Prefix+1st nonmetal) + (Prefix+2nd nonmetal-ide) Ex: H2O2 Dihydrogen dioxide CO2 Carbon dioxide |
|
|
|
Covalent Compounds (Formula Rules) |
Prefix = subscript Dihydrogen dioxide H2O2 Carbon dioxide CO2 Carbon tetrachloride CCl4 |
|
|
|
Polyatomic Ions (Formula Naming) |
Charges need to be balenced Magnesium (+2) Nitrite (-1)--- Mg(NO2)2 |
|
|
|
Transition Metals (Naming Rules) |
Metal+Roman numeral+nonmetal-ide CuS = Copper (II) Sulfide Cu2S = Copper (I) Sulfide |
|
|
|
Transition Metals (Formula) |
Charges need to be balenced Copper (II) Sulfide = CuS |
|
|
|
Acid Naming |
***Hydrogen bonded to NM*** Binary acids = Hydrogen + Polyatomic If p.a ends in ate:__ic acid If p.a ends in ite:___ ous acid HCL Hydrochloric Acid H2SO4 (tertiary ending in ate) Sulfuric acid H2SO3 (tertiary ending in ite) Sulfurous Acid |
|
|
|
Acids (Formula) |
***Hydrogen bonded to NM*** Charges need to be balanced Hydrochloric Acid: HCl Sulfuric Acid: H2SO4 Sulfurous Acid: H2SO3 |
