In symbolic form, the number of nucleons is denoted as a superscripted prefix to the chemical symbol (for example 3 He, 12 C, 13 C, 131 I, and 238 U). The letters m or f may follow the number to indicate metastable or fission isomers, as in 58m Co or 240f Pu. Subscripts and superscripts can also be used together to give more specific ...
The difference between superscript/subscript and numerator/denominator glyphs. In many popular computer fonts the Unicode "superscript" and "subscript" characters are actually numerator and denominator glyphs. Unicode has subscripted and superscripted versions of a number of characters including a full set of Arabic numerals. [1]
Superscripts and Subscripts is a Unicode block containing superscript and subscript numerals, mathematical operators, and letters used in mathematics and phonetics. The use of subscripts and superscripts in Unicode allows any polynomial , chemical and certain other equations to be represented in plain text without using any form of markup like ...
The Unicode Standard encodes almost all standard characters used in mathematics. [1] Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. [1]
Subscripts and superscripts should be wrapped in <sub> and <sup> HTML tags, respectively, with no other formatting info, with some exceptions (see below). The {} and {} templates are useful shortcuts to the HTML markup. Do not use the Unicode subscripts and superscripts ² and ³, or XML/HTML character entity references (² etc.).
Special care is needed with subscripted labels to distinguish the purpose of the subscript (as this is a common error): variables and constants in subscripts should be italic, while textual labels should be in normal text font (Roman, upright). For example:
Often used for finite fields, with a subscript to indicate the order. [26] Also represents a Hirzebruch surface or a free group, with a subscript to indicate the number of generators (or generating set, if infinite). U+1D53E: 𝔾 Represents a Grassmannian or a group, especially an algebraic group.
This is a stylistic variation on the more common + for a check and # (number sign) for checkmate. In chemistry, the double dagger is used in chemical kinetics to indicate a transition state species. On a cricket scorecard or team list, the dagger indicates the team's wicket-keeper. [32]
