Naming from the formula
Write the name of the first element. Write the name of the second element. Change the ending of the second element to
"IDE"
Put the correct prefix in front of each element to tell how many atoms of that element are in the molecule.
Carbon Oxygenoxidedi

Naming from the Formula
• Only use “mono” for the second element
• “ide” still only used for second element• CO2 = carbon dioxide; NOT
monocarbon dioxide. • H2O = dihydrogen monoxide

Try it
• SO2
• NH3
• N2H4
• CCl4• NO

Naming the formula from the name:
Dinitrogen monoxide Write the symbol of the first element. Write the symbol of the second element. Use the prefix in the name to acquire the correct subscript.
dinitrogen monoxide
N ON2O
