Consider an atom whose designation is given as 94 Pu 242. How many Protons are found in this atom?

Protons same in all isotopes. The number of nutrons varies to change to atomic weight

there are 94 because the atomic number is equal to the number of protons.


Thank You, Lance

    How does the structure if an atom relate to how electric charges form? I don't quite understand the question. All electrons and protons have charges. The charges do not "form", they are already there. They are part of every atom.
