What Happens When Magnesium Reacts With Oxygen?
- The alkaline earth metal is called magnesium. The second group of metals in the periodic table is known as Alkaline earth metals. They only have two electrons in their outer electron shell, which are very reactive.
- Magnesium has a high reactivity nature, which is why magnesium ribbons need to be cleaned before use.
- When a magnesium ribbon is exposed to air for a long period of time, the oxygen in the air reacts with the magnesium ribbon and gets oxidized into magnesium oxide.
⇒ 2Mg+ O2⟶2MgO
(The above-given reaction is an example of a combination as well as an oxidation reaction)
Why Magnesium Ribbon is Rubbed Before Burning?
Magnesium ribbon is rubbed before burning because it has a coating of basic magnesium oxide. The coating of magnesium oxide prevents the ribbon from burning as it slows down its burning.
