Which metal is represented by the symbol Be?

The correct answer is Beryllium, which is represented by the symbol Be in the periodic table of elements. Beryllium is a lightweight metal known for its high strength-to-weight ratio and is used in various applications, including aerospace and nuclear industries. The chemical properties of beryllium include its ability to form stable compounds and react with acids to produce hydrogen gas.

The other options listed do not correspond to the symbol Be. Bertrandium and Bericium do not exist as recognized elements in the periodic table, while Bismuth is identified by the symbol Bi. This highlights the importance of understanding chemical symbols and their corresponding elements in the study of chemistry and materials science.
