2 facts
2.1 Facts Interesting
  • Osmium logam ora oxidize ing online kajaba kang digawe panas.
  • Nanging yen digawe panas den iku formulir Osmium tetroxide, kang Highly beracun.
  • Samarium logam mbantu menehi pancingan metabolisme awak.
  • Samarium logam ana 1st diamati dening Jean Charles Galissard de Marignac ing Dydimia ing 1853.
