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 information about nuclides. For example, 235 92 U denotes an atom of uranium with 235 nucleons, 92 of which are protons. A chemical symbol can be completely ...
The most common superscript digits (1, 2, and 3) were included in ISO-8859-1 and were therefore carried over into those code points in the Latin-1 range of Unicode. The remainder were placed along with basic arithmetical symbols, and later some Latin subscripts, in a dedicated block at U+2070 to U+209F.

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 HTML or TeX.
These could also be used to make the important words on signs larger. In technical terms, the superior letter can also be called the superscripted minuscule letter. In modern usage, with word processors and text entry interfaces, superscript and superior letters are produced in the same way and look identical. Their distinction would refer to ...
A superscript letter generally referred to the letter omitted, but, in some instances, as in the case of vowel letters, it could refer to a missing vowel combined with the letter r, before or after it. It is only in some English dialects that the letter r before another consonant largely silent and the preceding vowel is "r-coloured".
Three variants of obelus glyphs. The dagger symbol originated from a variant of the obelus, originally depicted by a plain line − or a line with one or two dots ÷. [7] It represented an iron roasting spit, a dart, or the sharp end of a javelin, [8] symbolizing the skewering or cutting out of dubious matter.
Powers of unit symbols such as squares and cubes are expressed with a superscript exponent (5 km 2, 2 cm 3). Use the <sup> tag or {{sup}} template rather than the Unicode superscript characters such as ². Squared imperial and US unit abbreviations may be rendered with sq, and cubic with cu (15 sq mi, 3 cu ft).
