Web11 nov. 2024 · Answer: D. 30 protons, 39 neutrons, 30 electrons Explanation: The atomic number (Z) is the number of protons (p) in the nucleus. Since Z = 30, p = 30. In a neutral atom, the number of electrons (e) equals the number of protons. Since p = 30, e = 30 . The mass number (A) is the number of protons plus the number of neutrons (n). A = p + n poptropica backlot island sound editing
