    The answer to your question is Argon

    Explanation:

    Electron configuration given 1s² 2s² 2p⁶ 3s² 3p⁶

    To find the element whose electron configuration is given, we can do it by two methods.

    Number 1. Sum all the exponents the result will give you the atomic number of the element.

    2 + 2 + 6 + 2 + 6 = 18

    The element with an atomic number of 18 is Argon.

    Number 2. Look at the last terms of the electronic configuration

    3s² 3p⁶

    Number three indicates that this element is in the third period in the periodic table.

    Sum the exponents 2 + 6 = 8

    Number 8 indicates that this element is the number 8 of that period without considering the transition elements.

    The element with these characteristics is Argon.
