Going from a covalent name to formula guided practice – Not homework – Keep this resource sheet This is a fairly simple process which is basically the reverse of going from a name to a formula. Our example will be Dinitrogen Trisulfide Step 1: Write the chemical symbol of the first element with the corresponding subscript for its prefix The thing to keep in mind here is that if there is no prefix, then there is no subscript (imaginary 1). For example with Dinitrogen Trisulfide the Dinitrogen will be N2 as the prefix Di is associated with the subscript 2. Step 2: Write the chemical symbol of the second element with the corresponding subscript for its prefix. This time there will always be a prefix, but mono- means you will have no subscript. For example with Dinitrogen Trisulfide the Trisulfide will be S3 as the prefix Tri is associated with the subscript 3. Examples: Silicon Triodide Dinitrogen Tetrasulfide Carbon Monoxide Now you try: Carbon Hexafluoride Triarsenic Decabromide Tellurium Pentachloride Going from a covalent name to formula guided practice – Not homework – Keep this resource sheet This is a fairly simple process which is basically the reverse of going from a name to a formula.
