    That is the electron configuration for Chlorine (Cl). Remember that the p-orbital can only hold a maximum of 6 electrons. And six electrons means that it's a noble gas. Since it doesn't have 6 electrons, but instead, 5, that means that it must be the electron before noble gas in row 3.

    abb0t gives a good answer, although I think he might mean "element" rather than electron in his last sentence. Pedantic - probably?
