history
锇 is never used on its own outside chemistry. It is a modern phono-semantic coinage: the metal radical 钅 marks it as a metal and 我 supplies the sound for the element reading é. Coined in the same systematic way as the other metal-element names 铑, 铂 and 钯.
我 supplies the phonetic shape; in the systematic element reading the character is pronounced 锇. It carries no meaning here, the standard pattern for translated element names.
