 Livermorium is projected to be the fourth member of the 7p series of chemical elements and the heaviest member of group 16 ( VIA ) in the Periodic Table , below polonium . While it is the least theoretically studied of the 7p elements , its chemistry is expected to be quite similar to that of polonium . The group oxidation state of + 6 is known for all the chalcogens apart from oxygen which lacks available d @-@ orbitals for expansion of its octet and is itself one of the strongest oxidizing agents among the chemical elements . Oxygen is thus limited to a maximum + 2 state , exhibited in the fluoride OF2 . The + 4 state is known for sulfur , selenium , tellurium , and polonium , undergoing a shift in stability from reducing for sulfur ( IV ) and selenium ( IV ) through being the most stable state for tellurium ( IV ) to being oxidizing in polonium ( IV ) . This suggests a decreasing stability for the higher oxidation states as the group is descended due to the increasing importance of relativistic effects , especially the inert pair effect . The most stable oxidation state of livermorium should thus be + 2 , with a rather unstable + 4 state . The + 2 state should be about as easy to form as it is for beryllium and magnesium , and the + 4 state should only be achieved with strongly electronegative ligands , such as in livermorium ( IV ) fluoride ( LvF4 ) . The + 6 state should not exist at all due to the very strong stabilization of the 7s electrons , making the valence core of livermorium only four electrons . The lighter chalcogens are also known to form a − 2 state as oxide , sulfide , selenide , telluride , and polonide ; due to the destabilization of livermorium 's 7p3 / 2 subshell , the − 2 state should be very unstable for livermorium , whose chemistry should be essentially cationic , though the larger subshell and spinor energy splittings of livermorium as compared to polonium should stabilize Lv2 − slightly .
