    Answer: True

    Explanation: Every atom of the same element has the same atomic number of number of protons in its core. This is why chemists say that an atom is defined by its atomic number of the number of protons.

    Unlike neutrons and electrons, you can't change protons. You can change the number of neutrons and it will still be the same element, but one is going to be a little bit heavier or a little bit lighter than another.

    In addition, you can change electrons which creates

    ions or charged atoms.

    However, you can't change the protons.

    For example, hydrogen has 1 proton in its nucleus no matter what and helium has 2 protons in its nucleus no matter what and so on.
