Oxidation States in MgSF6

The video tutorial explains how to determine the oxidation numbers for each element in the compound MgSF6. It starts by identifying the oxidation states of magnesium and fluorine, which are +2 and -1, respectively. The tutorial then calculates the oxidation number for sulfur by ensuring the sum of all oxidation numbers equals zero, as MgSF6 is a neutral compound. The sulfur is determined to have an oxidation number of +4. The video concludes with a summary of the process and the final oxidation numbers.
