Did you know?
- In Japanese, the ending チン in アスタチン is a common phonetic adaptation for the English suffix '-tine', also seen in words like カフェイン 'caffeine' or ニコチン 'nicotine'.
- If a Japanese speaker sees アスタチン written in a non-scientific context, they might confuse it with a brand name or a character name due to the nature of katakana.
- The word アスタチン is written entirely in katakana, the alphabet used for foreign loanwords, because the element was named using Greek roots before entering Japanese.
