Naming Molecular Compounds

Naming Molecular Compounds. When naming salts, do we ever say the number of cation and anions?. No!. When naming molecular compounds, do we say the number of atoms of each element. Usually we do. But we say the numbers in Greek. One is. mono. Six is. hexa. Two is. di. Seven is.

  1. Naming Molecular Compounds

  2. When naming salts, do we ever say the number of cation and anions? No! When naming molecular compounds, do we say the number of atoms of each element Usually we do. But we say the numbers in Greek One is mono Six is hexa Two is di Seven is hepta Three is tri Eight is octa Four is tetra Nine is nona Five is penta Ten is deca

  3. Greek English Greek English Let’s practice the Greek number system. mono one tetra four tri three hepta seven hexa six penta five deca ten octa eight di two nona nine

  4. English Greek English Greek Let’s practice the Greek number system. five penta one mono seven hepta nine nona six hexa three tri eight octa two di four tetra ten deca

  5. One is mono Three is tri Five is penta Seven is hepta Nine is nona Two is di Four is tetra Six is hexa Eight is octa Ten is deca Using these greek numbers, name the following compounds: SCl2 – one sulfur & two chlorines sulfur dichloride PCl3 – one phosphorus & three chlorines phosphorus trichloride PCl5 – one phosphorus & five chlorines phosphorus pentachloride CO2 – one carbon & two oxygens carbon dioxide CO – one carbon & one oxygen carbon monoxide NO2 – one nitrogen & two oxygens nitrogen dioxide SO3 – one sulfur & three oxygens sulfur trioxide N2O5 – two nitrogens & five oxygens dinitrogen pentoxide

  6. One is mono Three is tri Five is penta Seven is hepta Nine is nona Two is di Four is tetra Six is hexa Eight is octa Ten is deca Using these greek numbers, give formulas for the following names: sulfur hexachloride SCl6 nitrogen trichloride NCl3 oxygen difluoride OF2 bromine trifluoride BrF3 diiodine tetroxide I2O4 dinitrogen monoxide N2O sulfur dioxide SO2 dinitrogen tetroxide N2O4
