Facts Interesting
- Seng logam ketemu (diwenehi) ing akeh formulir kaya granules, foil, bledug lan ing wangun bubuk.
- Sawise wesi, Seng logam kaloro paling akeh ing kerak bumi.
- Samarium logam mbantu menehi pancingan metabolisme awak.
- Samarium logam ana 1st diamati dening Jean Charles Galissard de Marignac ing Dydimia ing 1853.

Ulah lan Wuku
- Wis resistance karat lan Empu iku digunakake kanggo piring logam.
- wesi banget migunani; alloy Nichrome digunakake ing kumparan panas saka toasters lan open listrik.
- Magnet saka campuran kobalt Samarium luwih kuwat tinimbang wesi lan mula digunakake ing aplikasi gelombang mikro.
- Logam Samarium uga digunakake ing laser optik lan kaca tingal nyerep infra merah lan minangka penyerap neutron.
