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.

Angelic acid An organic acid found in garden angelica (Angelica archangelica), Umbelliferae, and many other plants. DAMN: Diaminomaleonitrile, a cyanocarbon that contains two amine groups and two nitrile groups bound to an ethylene backbone. Diabolic acid: A series of long-chain dicarboxylic acids with chains of different lengths.

The modern meaning of organic compound is any compound that contains a significant amount of carbon—even though many of the organic compounds known today have no connection to any substance found in living organisms. The term carbogenic has been proposed by E. J. Corey as a modern alternative to organic, but this neologism remains relatively ...
The main group elements are the elements of groups 1, 2, and 13–18 (i.e. the s-block and p-block). [5] The transition elements are the elements of groups 3–12 (i.e. the d-block) – this in particular includes group 12 (although some sources do not include it). [5] The inner transition elements are f-block elements. [2]
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Inorganic polymers can also be named in accordance with inorganic nomenclature, but the seniority of the elements is different from that in organic nomenclature. However, certain inorganic and inorganic-organic polymers, for example those containing metallocene derivatives, are at present best named using organic nomenclature, e.g., the polymer ...
