Verified step by step guidance1
Understand the naming convention for molecular compounds, which often uses Greek prefixes to indicate the number of atoms of each element present in the compound.
Identify the prefix 'di-' which means 2, and 'deca-' which means 10, so 'disulfur decafluoride' indicates a compound with 2 sulfur atoms and 10 fluorine atoms.
Translate the name 'disulfur decafluoride' into a chemical formula by placing the symbols for sulfur (S) and fluorine (F) with their respective quantities: S2F10.
Compare the given options to the formula derived from the name: S2F2, S2F10, SF6, and SF4, and determine which matches the correct formula for disulfur decafluoride.
Conclude that the correct formula representing disulfur decafluoride is the one with 2 sulfur atoms and 10 fluorine atoms, which is S2F10.
