convert/iupac

convert an atomic number to and from the temporary International Union of Pure and Applied Chemistry (IUPAC) name or symbol

 Calling Sequence convert(u, iupac, symbol)

Parameters

 u - symbol, string, or positive integer symbol - (optional); specify that an atomic number be converted to the IUPAC symbol

Description

 • The convert(u, iupac) command converts a positive integer representing an atomic number to a string representing its temporary IUPAC name.
 • The convert(u, iupac, symbol) command converts a positive integer representing an atomic number to a string representing its temporary IUPAC symbol.
 • The convert(u, iupac) command converts a string or symbol representing an IUPAC name or symbol to a positive integer representing its atomic number.
 • Temporary IUPAC names are used as placeholders until a proper name and symbol has been chosen for newly discovered elements.
 The name of an element is formed by replacing each digit in the atomic number with the corresponding name, and then appending um or ium. The um suffix is used if the last digit name ends in the letter i.
 The symbol of an element is formed by replacing each digit in the atomic number with the corresponding symbol, and then capitalizing the first symbol.
