What is the etymology of periodic table?
The table is termed “periodic” because it follows the periodic law – when chemical elements are arranged in order of increasing atomic number, elements with similar properties recur at intervals.
How did each element get its name?
New elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist. The names have to be unique and maintain “historical and chemical consistency”. No-one has yet named an element after themselves but many elements are named in tribute to important scientists.
