Mg loses two electrons to have an octet.
Oxygen gains two electrons to have an octet.
The ionic bond between ions results from the electrostatic attraction of opposite charges.
The final formula of magnesium oxide is MgO.
How does magnesium react with oxygen?
When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.
What type of bond is formed between magnesium and oxygen?
Magnesium (Mg) is able to bond with one oxygen (O) atom. The formula of the compound is MgO. You can see in the dot structure that the two atoms share four different electrons. When a bond is made with four electrons, it is called a double bond.
What happens to the magnesium and oxygen atoms when they form magnesium oxide?
When the reaction with oxygen occurs, these two electrons are donated by the magnesium, forming positively charged Mg2+ ions. The two electrons donated from one magnesium atom are taken up by an oxygen atom. Therefore, they readily take up these two electrons to form negatively charged O2- ions.
Does oxygen and magnesium form an ionic compound?
Magnesium oxide is considered ionic. This means that the bonds that hold magnesium and oxygen together are formed between atoms that give electrons or
