'S e eileamaid cheimigeach a tha ann am bohrium le samhla Bh agus àireamh atamach 107.

'S e meatailt trastach glè rèidio-bheò agus fuadain a tha ann. Tha an cor ogsaidicheadh VII cudromach sa' cheimigeachd de bhohrium. Chan eil ach aon co-thàthaidh bhohrium fhathast, bohrium ogsaiclòraid, BhO3Cl.[2]

Rinneadh caractarachd ri 11 iosatòpaichean de bohrium. Tha 270Bh, le leth-bheatha 3.8 mionaidean, as seasmhaiche.

Ann an 1976 rinn sgioba Yuri Oganessian aig an Co-institiud airson Rannsachadh Niùclasach còig ataman de dh'eileamaid 106, bohrium-262, nuair a bhuail iad biosmat-209 le niùclasan cròmium-54.[3] Ann an 1997 chaidh ainmicheadh air Niels Bohr, fiosaigiche às an Danmhairg.[4]

Tha bohrium glè thearc agus chan eil cleachdaidhean ann.
