The atomic mass of aluminum is 26.98 amu. Aluminum is one of the lightest elements, making it ideal for construction, transportation and other commercial uses.
Aluminum is a very common element, third in abundance only to silicon and oxygen. However, aluminum is too reactive to exist in a pure form naturally. Over 270 different aluminum compounds exist, the most common being bauxite. Aluminum metal has been removed from natural compounds for commercial use since the early 1900s. Generally, aluminum use is favorable because the metal is light, malleable and resistant to erosion. Finally, aluminum is very easy to recycle, which makes it a renewable resource for the planet.Learn More
Aluminum is valuable for several reasons: it is relatively light-weight, resists corrosion and lacks magnetic properties, making it a practical element for multiple purposes. Aluminum ranks among the most versatile elements. It resists sparking and damage from heat, making it suitable for use in heat-conducting equipment and components.Full Answer >
The percentage of aluminum in aluminum oxide is 52.93 percent. To find this percentage, it is necessary to know the atomic masses of aluminum and oxygen and the molecular formula Al2O3, which provides the number of atoms of aluminum and oxygen in aluminum oxide.Full Answer >
The atomic theory is that all matter is made up of tiny units or particles called atoms. This theory describes the characteristics, structure and behavior of atoms as well as the components that make up atoms. Furthermore, the theory states that all elements are made up of identical atoms.Full Answer >
