Text Solution

AI Generated Solution

To explain why SF₆ is known but SH₆ is not known, we can analyze the oxidation states and the properties of sulfur when bonded to different elements. ### Step-by-Step Solution: 1. **Understanding SF₆**: - SF₆ (sulfur hexafluoride) is a compound where sulfur (S) is bonded to six fluorine (F) atoms. - To find the oxidation state of sulfur in SF₆, we can use the formula: \[ ...
