What is the symbol for magnesium?

The correct answer is: Mg

The symbol for magnesium is Mg. This designation is derived from the element's name, which is based on the Latin "Magnesia." Each element on the periodic table is assigned a unique symbol that typically consists of one or two letters, with the first letter always capitalized. Magnesium is located in group 2 of the periodic table, known as alkaline earth metals, and plays a critical role in various biological and chemical processes. In the context of the other choices, it's important to distinguish the symbols of each element: Mn refers to manganese, Ca is for calcium, and Se denotes selenium. Knowing these symbols helps in understanding elemental identities and their interactions in chemical equations and reactions.
