Naming Rules and Conventions Element names are not proper nouns. Element symbols are one- or two-letter symbols. Halogen element names have an -ine ending. Nobel gas names end with -on. Newly discovered elements may be named for a person, place, mythological reference, property, or mineral.
How do you find the element name?
Each element is identified by the number of protons in its atoms. This number is the atomic number. The periodic table lists the elements in order of increasing atomic number. Each element has a symbol, which is one or two letters.
How do you name a newly discovered element?
When it comes to new elements, the IUPAC invites discoverers to propose names, which it then considers and puts up for approval. For these names, the IUPAC observes tradition and allows new elements to be named after: A mythological concept or character (including an astronomical object) Mineral or similar substance.
