Aluminum is a metallic element originating from the Latin word for alum. It has an atomic number of 13, atomic mass of 26.98, and three valence electrons. Aluminum is commonly found in the earth's crust combined with other elements and is extracted for use in car engines, soda cans, and other applications due to its light weight and ability to withstand heat. Aluminum was discovered in 1807 but was not isolated as a pure element until 1825 by H.C. Oersted.

Aluminum
● Aluminum is originated from the latin word “Alumen” meaning alum.
● The chemical symbol for aluminum is AL, the atomic mass is 26.98, and the atomic
number is 13.
● The number of valence electrons in the neutral atom of the element is three.
● Aluminum is in group and also in period 3. Some elements that are in the same group is
boron, gallium, and Indium.
● Aluminum isn’t necessarily found in nature other than in the earth's crust. It is commonly
mixed with other elements that form compounds.
● Aluminum is used for car engines and soda cans! The properties are varied between
aluminum being able to stand high temperatures, its light weight, and pure aluminum is
soft.
● Compounds:
Aluminum aceglutamide: human-made
Aluminum fluoride: naturally occurring
Aluminum azide: human-made
Aluminum hydride: human-made
Aluminum borohydride: human-made
● Aluminum was discovered in 1807 by Humphry Davy, he called it an unknown salt from
a metal but in 1825 physicist H.C. Oersted managed to produced aluminium by heating
potassium amalgam with aluminiu. H.C was the first to identify the element aluminum.
● Interesting fact: Back before silver and gold were discovered, aluminum was the most
expensive.
