    Can you identify the element with 27 protons by name?

    I'll start you off 1s2 2s2 2p6 3s2 3p6 the next 2 suborbitals are 4s and 3d

    Great! :-) From here we know that cobalt has 27 electrons (to balance out the 27 protons).

    And we need to add them in the order found here: http://chemwiki.ucdavis.edu/Inorganic_Chemistry/Electronic_Configurations

    Each orbital hold 2 electrons. s subshells have 1 orbital, p subshells have 3 orbitals, and d subshells have 5 orbitals.

    Do you see how @cwrw238 came up with the electron configuration up to argon?

    I guess she knows. But she doesn't know the sequence. Its 1s,2s,2p,3s,3p,4s,3d,4p,...... This way now @JoannaBlackwelder is right about the orbitals. so s can contain 2 electrons, p, 6 electrons, d, 10 electrons and f 14 electrons.
