Facts Interesting
- Barium gampang ngoksidasi ing udara.
- Kabeh senyawa beracun saka Barium bisa gampang larut ing banyu.
- Barium karbonat digunakake kanggo ngasilake racun tikus lan senyawa liyane Barium nitrat digunakake ing kembang api kanggo ngasilake werna ijo.
- Osmium logam ora oxidize ing online kajaba kang digawe panas.
- Nanging yen digawe panas den iku formulir Osmium tetroxide, kang Highly beracun.
