Explanation:
Detailed explanation-1: -Here, only fluorine shows a single oxidation state in all of its compounds.
Detailed explanation-2: -Here, only fluorine shows a single oxidation state in all of its compounds.
Detailed explanation-3: -Magnesium is a group 2 element with atomic number 12. As we can see, it can lose two electrons to gain the electronic configuration of Neon. Therefore, its oxidation number will be +2.
Detailed explanation-4: -For neutral magnesium to form a 2 + ion, it needs to lose two electrons. The oxidation number tells us how many electrons have been removed in order to form a chemical bond, so two lost electrons means an oxidation number of + 2 for the magnesium ion in M g O .
