    The element is oxygen.

    1s² 2s² 2p⁴

    Explanation:

    Let's consider the electron configuration of the excited state.

    1s² 2s² 2p³ 3s¹

    According to the Aufbau principle, the electron in 3s should occupy the shell with lower energy. The ground-state electron configuration is:

    1s² 2s² 2p⁴

    The differential electron is in the level 2. Then, the element is in the period 2.

    The electrons in the last level are 2 + 4 = 6. Then, the element is in the group VIA or 16.

    The element is oxygen.
