    Thank you for your question 😉

    Each element has its own atomic number; it is therefore impossible that two elements have the same atomic number!

    This principle is explained by the fact that the number of protons is characteristic of an element, and the number of protons is indicated by the atomic number.

    Hope that answers your question! Do not hesitate to come back if you have any other questions!
