    Answer is: [Xe] 6s².

    Barium is metal from second group of periodic table of elements.

    Barium has atomic number 56, it has 56 protons and 56 electrons.

    Electron configuration of barium atom:

    ₅₆Ba 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 6s².

    Xenon (symbol: Xe) is an element (noble gas) with atomic number 54, which means it has 54 protons and 54 electrons.

    Electron configuration of xenon atom:

    ₅₄Xe 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶.
