systematic-element-name-pmb

Translate between hypothetical elements' atomic number, their systematic element name, and their symbol.

In chemistry and physics, hypothetical chemical elements whose existence has not yet been proven are assigned a temporary systematic element name based on their Atomic number.

API

This module exports one function:

parse(input)

Translate input, which may be

• an atomic number given as a Number or as a string of decimal digits,
• a string with the systematic element name,
• or a string with the systematic symbol.

For valid inputs, returns an object like { Z: 123, symb: 'Ubt': name: 'Unbitrium' }.

For almost-valid inputs (e.g. non-standard letter case or lack of contraction for dounle "i" or triple "n"), two additional properties are added:

• fixed: Which field ('symb' or 'name') contains the corrected version of the input value.
• origInput: The original input value.

For invalid inputs, returns false.

Usage

see test/usage.mjs.

Range restriction

In chemistry, systematic element names are meant to be used only for elements with 3-digit atomic numbers. This library ignores this restriction, and will happily parse and produce systematic symbols that will conflict with the symbols of known elements.

See test/conflicts.mjs for examples.

Known issues

• Needs more/better tests and docs.
