Version: 2.2.98 (using KDE 4.3.3) OS: Linux Installed from: Fedora RPMs Kalzium says the electronic configuration of the 41th element, also known under the poetic name of Niobium, is "Kr 4d4". This is wrong and should be read "Kr 4d4 5s1" That's all, folks!!! (Kisses from Normandy under white snow)
I just patched the elements.xml file. Now Niobium shows the correct electronic configuration. Thanks hugues for pointing that out.
