Element Names
- The International Union of Pure and Applied Chemistry (IUPAC) is responsible for approving the official names of elements.
- Elements are named based on their properties, discovery, or the scientist who discovered them.
- Some elements are named after:
- Mythological figures (e.g., Titanium, Tantalum)
- Places (e.g., Francium, Germanium)
- Properties (e.g., Oxygen, Iodine)
- Scientists (e.g., Curium, Rutherfordium)
- Elements with atomic numbers 1-10 have Latin roots:
- Hydrogen (hydrogenium)
- Helium (helium)
- Lithium (lithium)
- ...and so on
- Elements with atomic numbers 11-30 have Latin roots with Greek prefixes:
- Sodium (natrium)
- Magnesium (magnesium)
- Aluminum (aluminium)
- ...and so on
- Elements with atomic numbers 31-103 have a combination of Latin and Greek roots:
- Germanium (germanium)
- Arsenic (arsenicum)
- Selenium (selenium)
- ...and so on
- Elements with atomic numbers 104 and above have temporary names based on their atomic number:
- Unnilquadium (104)
- Unnilpentium (105)
- ...and so on
