Facts Interesting
- Sumber utama Kobalt minangka produk sampingan saka pertambangan logam tembaga lan nikel.
- Logam kobalt bisa dipikolehi saka unsur liyane kayata Oksigen, Sulfur lan Arsenik.
- Uga digunakake ing proses electroplating amarga nuduhake sifat anti cession.
- Iron ora tansah Magnetik ing alam, allotrope sawijining ferromagnetic lan B allotrope punika nonmagnetic.
- getih kasusun Iron in molekul hemoglobin kanggo nransfer Oksigen ing awak.
