Write The Chemical Formula For Beryllium Selenide.

The chemical formula for beryllium selenide is BeSe. It consists of one beryllium atom and one selenium atom, with each atom contributing one valence electron to form a stable ionic compound. The beryllium atom has a +2 charge, while the selenium atom has a -2 charge, resulting in an overall neutral compound. Beryllium selenide is a white solid with a high melting point and is typically synthesized by reacting beryllium metal with selenium powder under high temperature and pressure conditions.
