Enter the symbol for the element represented by the following electronic configuration.

???
How does this work?

    Count the electrons. Ar has 18 and add 8 more for 26. Look up element #26 on the periodic table. It helps if you separate them a little better when typing
    [Ar] 4s2 3d6; otherwise it appears as 4s23
