Element List - Atomic Number, Element Name and Symbol

Heres a list of the chemical elements ordered by increasing atomic number. The names and element symbols are provided. Each element has a one- or two-letter symbol, which is an abbreviated form of its present or former name. The element number is its atomic number, which is the number of protons in each of its atoms.

Halogen names usually end with -ine. Noble gas names usually have the -on ending. Elements having names not following this naming convention tend to be ones known and discovered long ago. Future Element Names Right now, the periodic table is complete in that there are no remaining spots in the 7 periods. However, new elements may be synthesized or discovered. As with other elements, the atomic number will be determined by the number of protons within each atom. The element name and element symbol will need to be reviewed and approved by the IUPAC before inclusion on the periodic table. The element names and symbols may be proposed by the element discoverer, but often undergo revision before final approval. Before a name and symbol are approved, an element may be referred to by its atomic number (e.g., element 120) or by its systematic element name. The systematic element name is a temporary name that is based on the atomic number as a root and the -ium ending as a suffix. For example, element 120 has the temporary name unbinilium.
