Burenium

Burenium, bibioctium (Bbo), or dvi-flerovium is the hypothetical chemical element with the symbol Bm and the atomic number 228. Is it the post-transition metal in the Crystallogens group (Carbon family, 9p2 coordinate) below Bornium (Bn), 168 element. Named after Martin van Buren. Under normal conditions, Burenium is a black refractory metal due to relativistic effects. Like all chemical elements with an atomic number greater than 82, Burenium has no stable isotopes. The most stable of these, 716Bm, has a half-life of about 4 milliseconds. There is not much to say about it.
