Total valence electrons of two chromium atoms, seven oxygen atoms and two negative charges are considered to draw the Cr 2 O 72- Lewis structure. There are double bonds and single bonds in the lewis structure of Cr 2 O 72- ion.
WebDec 14, 2015 · This happens in Chromium, as one #4s# electron moves to the #3d# sublevel. Why? There are two main reasons: The #3d# orbital is slightly lower in energy, and minimizing repulsions in the #4s# orbital by moving one of the #4s# electrons to a close-lying #3d# orbital minimizes the ground-state energy of chromium. http://www.chemicalelements.com/elements/cr.html
