 3 are predicted to form preferentially in flerovium @-@ containing solutions . The sd hybridizations would be possible as the 7s and 6d electrons in flerovium share approximately the same energy , perhaps making even higher oxidation states like + 6 possible with extremely electronegative elements , such as in flerovium ( VI ) fluoride ( <unk> ) . In general , the spin @-@ orbit contraction of the 7p1 / 2 orbital should lead to smaller bond lengths and larger bond angles : this has been theoretically confirmed in FlH2 .
