the mass number or nucleon number of an element in chemistry [6] the Helmholtz free energy of a closed thermodynamic system of constant pressure and temperature [7] a vector potential, in electromagnetics it can refer to the magnetic vector potential [8] with a subscript, an alternating group on that many objects; an Abelian group in abstract ...
Thus "H₂O" (using a subscript 2 character) is supposed to be identical to "H 2 O" (with subscript markup). In reality, many fonts that include these characters ignore the Unicode definition, and instead design the digits for mathematical numerator and denominator glyphs, [3] [4] which are aligned with the cap line and the baseline, respectively.
Subscripts "1" and "2" denote symmetry and antisymmetry, respectively, with respect to a nonprincipal rotation axis. Higher numbers denote additional representations with such asymmetry. Single prime ( ' ) and double prime ( '' ) superscripts denote symmetry and antisymmetry, respectively, with respect to a horizontal mirror plane σ h , one ...
Example of subscript and superscript. In each example the first "2" is professionally designed, and is included as part of the glyph set; the second "2" is a manual approximation using a small version of the standard "2". The visual weight of the first "2" matches the other characters better.
This is a list of letters of the Latin script. The definition of a Latin-script letter for this list is a character encoded in the Unicode Standard that has a script property of 'Latin' and the general category of 'Letter'. An overview of the distribution of Latin-script letters in Unicode is given in Latin script in Unicode.
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 ...
For example, the phosphate ion containing radioactive phosphorus-32 is [32 PO 4] 3−. Also a study involving stable isotope ratios might include the molecule 18 O 16 O. A left-hand subscript is sometimes used redundantly to indicate the atomic number. For example, 8 O 2 for dioxygen, and 16 8 O 2 for the most abundant isotopic species of dioxygen.
Examples: H He C Ca. Attached subscripts or superscripts specifying a nucleotide or molecule have the following meanings and positions: The nucleon number (mass number) is shown in the left superscript position (e.g., 14 N) The number of atoms of a nucleotide is shown in the right subscript position (e.g., 14 N 2)
