Alchemical Symbols is a Unicode block containing symbols for chemicals and substances used in ancient and medieval alchemy texts. Many of the symbols are duplicates or redundant with previous characters. [3] Few fonts support more than a few characters in this block as of 2021. One that does and is free for personal use is Symbola 14.0.

In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds.
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols , normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.
