Facts Interesting
- Gadolinium ora ketemu gratis ing alam, Empu iku ora logam native.
- metal Gadolinium ditemokaké ing mineral Monazite lan bastnaesite.
- 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.
