Answer:

Number of protons is 82 and number of neutrons is 125.

Explanation:

Its mass number is 207 and atomic number is 82 is Lead.

Since it's atomic number is 82 means there are 82 electrons in it and number of electrons is equal to number of protons hence 82 .

And for number of neutrons just subtract number of protons from mass number like 207-82=125.
