Nezve Roentgenium
Roentgenium isimbi yakagadzirwa nevanhu, ine simba rakakura re radioactive uye inofungidzirwa kuti inoenderana negold.
Mashandisiro & Maapplication
No zvakajairika maapplication. Scientific research chete.
Nhoroondo yemitambo
Roentgenium inofungidzirwa kuti ndiyo inonyanya electronegative metal nekuda kwerelativist effects paelectron orbitals.
