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.
- Galena Mineral ngandhut meh 87% saka logam Lead ing, Galena punika sulfide Mineral.
- Sumber kasedhiya paling saka logam Lead dina iku dening ulang batre automobile.

Ulah lan Wuku
- 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.
- Sampeyan uga dipigunakaké ing insecticides, alami rambute lan minangka aditif anti-nuthuk kanggo bensin. Nanging kabeh iki dilarang déning pamaréntah minangka logam Lead dikenal kanggo ngrugekake kanggo kesehatan.
