What is the atomic symbol for Magnesium?

The atomic symbol for an element is a one- or two-letter abbreviation derived from its name, usually based on its English or Latin name. For magnesium, the symbol "Mg" is used in the periodic table, representing the element's identity and distinguishing it from other elements. This symbol is derived from the Latin name for magnesium, "magnesia."

Using "Mg" allows for universal understanding in the scientific community, ensuring clear communication regarding chemical compositions and reactions involving magnesium.

The other options do not represent the atomic symbol for magnesium. The single letter "M" is not specific enough, as it could stand for various elements starting with that letter. "Ma" is not an accepted symbol for magnesium, and "Mg2+" represents a magnesium ion with a positive charge, which is different from the elemental form. Thus, "Mg" is the appropriate choice as it accurately represents magnesium in its atomic form.
