What Is the Mercury Element Symbol?

Hg identifies the element mercury in periodic tables, chemical formulas, and scientific text. The capitalization is part of the symbol: HG, hg, and H g are not equivalent element notation.

How to Use and Format the Mercury Element Symbol

Write Mercury Element Symbol as Hg, with capital H and lowercase g. The encoded sequence is U+0048 U+0067. Preserve the capitalization when the symbol appears in a periodic table, formula, equation, database field, or laboratory label.

This page covers Hg as the element symbol for mercury. It does not treat mmHg as the same notation, and it does not use Hg as a generic abbreviation for metal. Add readable context when a non-specialist reader might not recognize the element symbol.

Write capital H followed by lowercase g
Keep Hg together as one element symbol
Add subscripts and charges only when the chemical formula requires them
Distinguish Hg from the pressure unit expression mmHg
Use UTF-8 text or complete numeric references in HTML
Add the word mercury when the context is not obvious
Preserve capitalization in headings, tables, and database exports
Verify the pasted sequence is U+0048 U+0067

Common Mercury Element Symbol Mistakes

Writing HG or hg instead of Hg
Confusing Hg with H or Mg
Treating mmHg as the element symbol alone

This page covers Hg as the IUPAC element symbol for mercury. It is not a generic metal abbreviation and it is not the complete pressure unit expression mmHg.

More About the Mercury Element Symbol

Mercury Element Symbol uses Hg, the IUPAC element symbol for mercury, atomic number 80. The sequence contains LATIN CAPITAL LETTER H followed by LATIN SMALL LETTER G, encoded as U+0048 U+0067. In chemistry, element-symbol capitalization is significant, so Hg should not be changed to HG or hg.

Use Hg when naming mercury as an element or when it forms part of a chemical formula. Examples include Hg, Hg²⁺, HgCl₂, and HgO. Subscripts, superscript charges, coefficients, and state symbols belong to the larger formula; the base element symbol remains capital H plus lowercase g. The page therefore treats Hg as scientific notation rather than as a decorative two-letter monogram.

Hg must also be distinguished from mmHg. The expression mmHg is a pressure unit name based on millimetres of mercury, while Hg by itself is the element symbol. It is also different from H for hydrogen, Mg for magnesium, and other letter sequences that can look similar in a compact font. When the symbol appears in a table, label, or interface, include the readable word “mercury” when the audience may not know the abbreviation.

For digital use, copy the complete sequence Hg. UTF-8 text is preferable because it remains searchable and selectable. HTML can also represent the letters with decimal references H g or hexadecimal references H g. Verify the final capitalization after pasting.
