What Is The Chemical Formula For Aluminium Selenide?

The chemical formula for aluminium selenide is Al2Se3. This compound is composed of two aluminum (Al) atoms and three selenium (Se) atoms, which form a crystalline solid with a tetragonal structure.

Each aluminum atom in Al2Se3 has a +3 oxidation state, while each selenium atom has a -2 oxidation state. To balance the charges, two aluminum atoms combine with three selenium atoms to form one molecule of Al2Se3.

Aluminium selenide can be prepared by reacting aluminum powder with selenium powder at high temperatures under an inert atmosphere. It is a semiconductor material that finds applications in optoelectronics, solar cells, and other electronic devices.
