Accessed on-line: 11/13/2020 E. Clementi, D.L.Raimondi, and W.P. The following are "Clementi-Raimondi" effective nuclear charges, Zeff. Niobium is a lustrous, grey, ductile, paramagnetic metal in group 5 of the periodic table (see table), with an electron configuration in the outermost shells atypical for group 5. Introduces stoichiometry and explains the differences between molarity, molality and normality. Chemical Properties of Niobium Please share and/or link to this page if you find it useful or informative. What is the electron configuration for Nickel in terms of the nearest noble gas? We are a great educational resource! Molar mass calculations are explained and there is a JavaScript calculator to aid calculations. Comprehensive data on the chemical element Niobium is provided on this page; including scores of properties, element names in many languages, most known nuclides of Niobium. The periodic table is structured so that elements with the same type of valence electron configuration are arranged in columns. A representation of the atomic spectrum of niobium. All rights reserved. The electron affinity of niobium is 86.1 kJ mol‑1. Reinhardt, J. The M shell contains 3s, 3p, and 3d, and can carry 18 electrons. Use online or print pages out as classroom handouts. These effective nuclear charges, Zeff, are adapted from the following references: I am grateful to Gwyn Williams (Jefferson Laboratory, Virginia, USA) who provided the electron binding energy data.

Compact Fluorescent Lights (CFLs): Are They Worth the Switch? The chemical element with the atomic number 41 is niobium; the electron configuration is:[Kr]4d4.5s1. The reason is that the 5s and 4d energy levels are quite close and certain electronic arrangements can result in the levels being slightly different than expected.
