Naming Binary CompoundsNaming Binary Compounds
• Write the name of the 1Write the name of the 1stst element element
• Add part of the name of the 2Add part of the name of the 2ndnd elementelement
• End the 2End the 2ndnd name with “ide” name with “ide”– Example: NaCl Example: NaCl
Sodium and ChlorSodium and Chlorineine
Sodium ChlorSodium Chlorideide
