How to Use and Format the Magnesium Element Symbol

Format Mg according to its role as Magnesium Element Symbol. Mg is the chemical element symbol for magnesium, atomic number 12. The symbol uses capital M followed by lowercase g. The encoded form is U+004D U+0067; preserve the complete sequence, capitalization, subscripts, and superscripts exactly as shown.

This page covers Mg as the element symbol for magnesium. It is not Hg for mercury, mg for milligram, or a complete magnesium compound formula. Add nearby readable wording when the notation appears outside a specialist chemistry context.

Write the element symbol exactly as Mg
Preserve uppercase and lowercase letters
Keep the complete sequence together when copying
Add subscripts or superscript charges only when the formula requires them
Define the element name for non-specialist readers
Use UTF-8 text or complete numeric references in HTML
Do not substitute a similar abbreviation or variable
Verify the encoded sequence is U+004D U+0067

Changing the capitalization of Mg
Confusing the element symbol with a unit or variable that uses the same letters
Dropping a charge or subscript from a larger chemical formula

How Magnesium Element Symbol differs

This page covers Mg as the element symbol for magnesium. It is not Hg for mercury, mg for milligram, or a complete magnesium compound formula.

More About the Magnesium Element Symbol

Mg is the chemical element symbol for magnesium, atomic number 12. The first letter is uppercase and the second is lowercase. That distinction is essential because Mg and mg do not mean the same thing: Mg names the element, while mg is the SI unit symbol for milligram.

In formulas, Mg may stand alone in a periodic-table entry or appear as part of compounds and ions. Mg²⁺ records a magnesium ion, MgO is magnesium oxide, and MgCl₂ is magnesium chloride. The charge or subscript belongs to the full expression; the element symbol itself remains capital M plus lowercase g.

A compact font can make Mg look close to Hg, the symbol for mercury. The two sequences are different and should not be substituted. When transcribing laboratory notes or importing data, verify both letters rather than relying only on the overall shape. An accessible label can state “magnesium” when the context does not already identify the element.

The text sequence for Mg is U+004D U+0067. In HTML, use literal UTF-8 Mg, decimal references M g, or hexadecimal references M g. Keeping the notation as text allows it to be searched, copied, and read by assistive technology.

This page is limited to Mg as chemistry notation. It does not treat lowercase mg as an alternate spelling, and it does not use Hg, Mn, or another nearby-looking element symbol as a variant.
