 In the periodic table of the elements , it is a transactinide element in the p @-@ block . It is a member of the 7th period and is the heaviest known member of the carbon group . Initial chemical studies performed in 2007 – 2008 indicated that flerovium was unexpectedly volatile for a group 14 element ; in preliminary results it even seemed to exhibit properties similar to those of the noble gases . More recent results show that flerovium 's reaction with gold is similar to that of copernicium , showing that it is a very volatile element that may even be gaseous at standard temperature and pressure , that it would show metallic properties , consistent with it being the heavier homologue of lead , and that it would be the least reactive metal in group 14 .
