In Taiwan chemistry textbooks the element is written 鍅, while the mainland writes it 钫.
Tips
usage
鍅 is the Taiwanese standard form for the element francium (Fr); mainland China uses 钫 (fāng). The Taiwan reading fǎ is borrowed from the second syllable of the Latin name (Fran-cium → 法-).
memory
The 钅 (metal) radical signals it is a metal; the 法 phonetic gives the fǎ reading and also evokes France — appropriate, since francium was discovered by French chemist Marguerite Perey in 1939.
