Magnesium

Magnesium is a highly flammable metal that is easy to ignite when powdered or shaved into thin strips. It is, however, difficult to ignite in mass or bulk. Once ignited, it is difficult to extinguish, being able to burn in both nitrogen (forming magnesium nitride), and carbon dioxide (forming magnesium oxide and carbon ).

Periodicity – Chemistry

Since oxidation is so easy, the reverse, reduction, is difficult, which explains why it is hard to isolate the elements.
