facts
Facts Interesting
  • 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.
