I-About Beryllium
I-Berkelium yi-actinide ekhanyayo, emhlophe ekhanyayo. Yasetyenziswa njengezinto eziphambili zokuvelisa i-element 117 (tennessine).
Iinkqubo
Izinto ezimiselweyo zokuvelisa izinto ezinzima kunye nokukhangela kwezobunjineli.
Inyathelo 1:
In ngo-2009, abaphandi bavelise ii-milligrams ezingama-22 ze-berkelium-249 ngaphezulu kweentsuku ezingama-250 ukwenza i-element 117.
