Hace 2 días · Niobium, 41Nb. body-centered cubic (bcc) ( cI2) Niobium is a chemical element; it has symbol Nb (formerly columbium, Cb) and atomic number 41. It is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to pure titanium, [5] and it has similar ductility to iron.
Hace 4 días · Flerovium is the heaviest known member of group 14, below lead, and is projected to be the second member of the 7p series of elements. Nihonium and flerovium are expected to form a very short subperiod corresponding to the filling of the 7p 1/2 orbital, coming between the filling of the 6d 5/2 and 7p 3/2 subshells.
Hace 5 días · Elements 112–118 (copernicium, nihonium, flerovium, moscovium, livermorium, tennessine, and oganesson) may be post-transition metals; insufficient quantities of them have been synthesized to allow sufficient investigation of their actual physical and chemical properties.
Hace 2 días · In 2015, it was declared that the seventh period of the periodic table was completed with discoveries of Z = 113 (nihonium), 115 (moscovium), 117 (tennesine) and 118 (oganesson). Immediately, nuclear physicists began a challenge to pioneer the eighth period starting with the 119th element.
