Ulah lan Wuku
- Technetium punika logam radioaktif lan Empu iku digunakake kanggo pasinaon medical lan risèt liyane.
- 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.
