Write the expected electron configurations for each of the following atoms. I know that an electron will move from the ns orbital to the (n-1)d orbital because of the half-filled and fully-filled ones having extra stability, but 4d4 is neither half-filled nor fully-filled. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. This list of electron configurations of elements contains all the elements in increasing order of atomic number.. To save room, the configurations are in noble gas shorthand. Your formula predicts 9 valence electrons (2+8+18+9), which is false. Tantalum was named after Tantalus, father of Niobe.
