Magnesium is a chemical element with symbol Mg and atomic number 12. Magnesium only occurs naturally in combination with other elements. It is the one of the least dense of all metals and burns in air with a brilliant-white light. Magnesium is a highly flammable metal, especially when cut into small pieces.

Magnesium is used in the airline industry. From the passage above state one property of the magnesium that is desirable and explain how this might be an advantage.

I bet it is the density. What would be of more interest is the density-strength ratio, but it does not write of that.

One property of magnesium that is desirable in the context of the airline industry is its low density.

To explain why this property is advantageous, we need to understand the concept of density. Density is a measure of how much mass is contained in a given volume. In simpler terms, it indicates how light or heavy a material is for its size.

In the case of magnesium being used in the airline industry, its low density is a significant advantage. Airplanes need to be as light as possible to maximize fuel efficiency and reduce overall costs. By using magnesium, which is one of the least dense metals, the weight of the aircraft can be reduced.

A lighter aircraft requires less fuel to fly, which means reduced fuel consumption and lower carbon emissions. Additionally, lower weight can increase the payload capacity of the aircraft, allowing it to carry more passengers or cargo without compromising safety.

The low density of magnesium also contributes to its other desirable property in the airline industry, which is its high strength-to-weight ratio. Despite being lightweight, magnesium exhibits good strength, making it suitable for structural components in aircraft construction. It can help ensure the structural integrity of the aircraft while keeping its weight low, resulting in improved performance and efficiency.
