Which Element Has the Symbol Al?
Answer – Aluminum is the element with the symbol Al.
Explanation:
Aluminum is a lightweight, durable metal with atomic number 13. It is a part of Group 13 (or Group IIIA) of the periodic table and is a solid at room temperature.
The name ‘aluminum’ comes from alumen, which is the Latin word for alum (potassium aluminum sulfate). While the American spelling remains ‘aluminum,’ the preferred UK spelling is ‘aluminium,’ which is in line with the names of other metals like sodium, potassium, and so on. The symbol Al is thus derived from its name, which was assigned by chemist Sir Humphry Davy.
The metal is abundant in the Earth’s crust. In fact, it is the third most common element there, making up about 8.23% of it. However, it is present largely as a compound rather than in its raw state; bauxite is the main ore from which aluminum is extracted.
Due to its malleability and conductivity, aluminum finds abundant use in automobiles, construction, cookware, wiring, and consumer appliances. Its most popular alloy duralumin is used widely for manufacturing aircrafts. Potassium aluminum sulfate, or alum, is an aluminum compound that has been used for dyeing and medical purposes for centuries.
