Facts Interesting
- Rubidium logam unsur 16 paling umum ditemokake ing lemah ndhuwur bumi.
- metal Rubidium uga ditemokake ing mineral uga banyu segara.
- Unsur cilik sing alami kalebu Kadmium.
- Kadmium dibebasake menyang atmosfer kanggo ngontrol letusan gunung geni lan kebakaran alas.
- Kang digunakake kanggo electroplating saka Steel kanggo resistance karat.
- Bisa nyerep neutron lan digunakake ing reaktor nuklir kanggo ngontrol fisi atom.

Ulah lan Wuku
- aplikasi utama Rubidium iku ing Manufaktur kaca.
- Rubidium bisa banget gampang njaluk ionized lan Empu iku digunakake kanggo mesin ion, nanging isih kurang efisien tinimbang sing saka Caesium.
- Wis Efesus banget winates minangka logam beracun lan bisa nimbulaké cacat lair, kanker, etc.
- Meh 80% saka logam kadmium digunakake ing Nikel Baterei kadmium lan saiki lagi njupuk diganti karo isotop nikel.
