Aluminum Periodic Table

Aluminum is a chemical element with the symbol Al and atomic number 13 in the periodic table. It is a silvery-white, soft, non-magnetic metal that belongs to the group of post-transition metals. Aluminum is the third most abundant element in the Earth's crust, after oxygen and silicon, and makes up about 8% of the crust by weight.

In the periodic table, aluminum is located in period 3 and group 13 (also known as the boron group). Group 13 elements have three valence electrons, which means they tend to form compounds with three other atoms or ions. Other elements in this group include boron, gallium, indium, and thallium.

Aluminum has a relatively low atomic mass of 26.98 u and a melting point of 660.32 °C (1220.58 °F). It is a good conductor of heat and electricity, and is resistant to corrosion due to the formation of a thin, protective oxide layer on its surface when exposed to air.

Aluminum and its alloys have a wide range of uses in modern industry and technology. It is commonly used in construction materials, transportation (such as airplanes and cars), electrical transmission lines, packaging, and consumer goods. Aluminum is also an important component of many everyday items, such as beverage cans, cooking utensils, and foil.

However, aluminum can be toxic to some organisms in high concentrations, and there is ongoing research into its potential health effects on humans.
