Help with electron configuration?

  1. Sep 16, 2013 #1
    I don't understand it.
    I was absent the day it was introduced so I'm behind.
    I'm trying to learn from google but I cant figure it out.
    I thought I understood but I guess not.
    I picked a random element off the periodic table.
    I know thats sub level d
    row 5
    column 11
    So I thought it was just 5D11
    I looked up the electron configuration for it and I got
    [Xe] 4f14 5d10 6s1
    Any guidance?
    Because I'm clearly lost.

    You happened to pick an element that has an exception to the rules->bad break! The wiki article http://en.wikipedia.org/wiki/Electron_configuration has a fairly good explaination as to what order to write the shells and how many electrons can fit in each.

    Finally, in case you were confused, the { [Xe] "other stuff" } notation refers to the configuration of [Element] plus the additional electron configuration for the working element. Space saving technique.
