Oct 29, 2012 · As cited in an answer to this question, the ground state electronic configuration of niobium is: Nb: [Kr] 5sX1 4dX4 N b: [K r] 5 s X 1 4 d X 4. Why is that so? What factors stabilize this configuration, compared to the obvious 5sX2 4dX3 5 s X 2 4 d X 3 (Aufbau principle), or the otherwise possible 5sX0 4dX5 5 s X 0 4 d X 5 (half-filled shell)?

You can compare Hg vs Nb on more than 90 properties like electronegativity , oxidation state, atomic shells, orbital structure, Electronaffinity, physical states, electrical conductivity and many more.

铌（Niobium），化学符号Nb，原子序数为41，是一种过渡金属元素。铌单质是一种带光泽的灰色金属。高纯度铌金属的延展性较高，但会随杂质含量的增加而变硬。铌对于热中子的捕获截面很低，因此在核工业上有相当大的用处。

The Hg-Nb (Mercury-Niobium) System C. Guminski University of Warsaw Equilibrium Diagram Experimental studies on the Hg-Nb system have been mainly solubility determinations and compatibility tests of solid Nb in liquid Hg. A speculative phase diagram (Fig. 1) has been con- structed on the basis of these studies.
