Sulfur Hexaflouride

#### Work Step by Step

"S" is the chemical symbol for sulfur. Because Sulfur comes at the beginning of the chemical formula and there is only one sulfur, no prefix is necessary. There are six fluorine atoms, so the prefix for the chemical name is "hexa" Because fluorine comes at the end of the name, it is necessary to change it from fluorine to fluoride. As a result, $F_6$ becomes hexafluoride. Thus, the name for $SF_6$ is Sulfur Hexaflouride.
