About Niobium
Niobium is a chemical element with the symbol Nb and atomic number 41, meaning every atom has 41 protons in its nucleus. It is classed as Transition metal and is a solid at room temperature. Its atomic mass is about 92.906 atomic mass units (u).
On the periodic table, Niobium sits in group 5, period 5, which determines how many electron shells it has and how it tends to react with other elements.
Uses of Niobium
In daily life and industry, Niobium is used for Superconductors. These uses are closely tied to the typical properties of elements in the Transition metal category.
Electron Structure of Niobium
Using a simplified electron shell model (at most 2 electrons in the first shell, 8 in the second, 18 in the third, and so on), Niobium has 4 electron shells, with an approximate arrangement of 2, 8, 18, 13 electrons from the innermost shell to the outermost. This is a simplified learning model, not the full electron configuration that accounts for the s, p, d and f subshells.
