Answer:
okay in order to get the number of protons in the isotope we see below of the isotope which is an ion 35 which is the atomic number is the number of protons or the number of electrons before becoming an ion is 35 so the number of electrons will be 36 because the number of protons and electrons are the same but decide gain one electron to 35 + 1 you get 36 and in order to get the number of neutrons will take 80 - 35 to get 45 which is the number of neutrons because number of neutrons is equal to atomic mass and atomic number.
