    The answer to your question is: letter A.

    Explanation:

    To solve this question, we must consider the total number of electrons that can be placed in each orbital.

    Orbital Number of electrons

    s 2

    p 6

    d 10

    f 14

    Options given

    A. 1s² 2s² 2p⁶ 3s² This electron configuration is correct because

    is in agreement with the number of electrons

    allowed in each orbital and the correct order

    of them.

    B. 1s² 2s² 2p⁶ 3s² 3d⁴ This electron configuration is incorrect because

    3d⁴ goes after 3p.

    C. 1s² 2s² 2d¹⁰ 2p³ This option is incorrect because 2d¹⁰ does not

    exist.

    D. 1s² 2s^s 2p³ 2d¹⁰ This option has 2 mistakes, s as a power does

    not exist and 2d¹⁰ is also incorrect.
