Why is magnesium so reactive, compared to other elements like zinc and aluminum?

Magnesium is easier to lose electrons than zinc and aluminum, so other elements and compounds such as oxygen, water, halogen, etc. will react violently with atoms that easily lose electrons. As shown in the figure below, the electronegativity of magnesium is 3, the electronegativity of zinc is 6, the electronegativity of aluminum is 6, the lower the electronegativity, the easier it is to lose atoms, and magnesium is more than zinc and aluminum is. Although more reactive, magnesium is not the most active metal, it is
All metals form cations. In fact, the metal is made up of these cations. Here, the electrons belonged to the ion swimming ions. This electron is called "delocalization". The more active metal is more likely to lose these electrons, so when it reacts with oxygen - this characteristic white flame is generated - it violently throws the electrons into oxygen. The elements you mentioned, aluminum and zinc are not easy to lose electronics
However, aluminum and zinc are still very reactive compared to well-known metals such as iron or copper. However, they do not corrode excessively in the air, or they are so reactive that they form a protective oxide coating as they come in contact with air.
Iron is one of the most basic elements of our body (the other elements are calcium, copper, magnesium, zinc, cobalt, magnesium). And it contributes to the formation of hemoglobin. It is worth noting that elements such as aluminum are not naturally formed in our body and that they are not necessary for human survival. In the last century, as a result of the Industrial Revolution, the manufacturing technology advanced, aluminum and steel were used to manufacture cooking utensils. In addition, our society saw the emergence of technology like Teflon coating which changed the way we cook our food. Steels as iron-carbon alloys solve many of the problems associated with excavators such as rust, durability and ease of manufacture, but it is also one of the fundamental elements of adding iron to our diet Is removed. Aluminum cookware with the highest thermal conductivity, on the other hand, is still the most popular in the world.
Magnesium is easier to lose electrons than zinc and aluminum, so other elements and compounds such as oxygen, water, halogen, etc. will react violently with atoms that easily lose electrons. As shown in the figure below, the electronegativity of magnesium is 1.3, the electronegativity of zinc is 1.7, the electronegativity of aluminum is 1.6, the lower the electronegativity, the easier the atom to lose, the more magnesium than zinc and aluminum It is. Although more reactive, magnesium is not the most active metal, it is
