The correct answer is:c. 10 protons, 10 electrons, and 9 neutrons.Explanation:The isotope
contains 10 protons, 10 electrons, and 9 neutrons. The atomic number (Z) is 10, indicating the number of protons, and the mass number (A) is 18. The number of neutrons is calculated as A - Z, which is 18 - 10 = 8. Since the isotope is neutral, the number of electrons is equal to the number of protons, which is 10.
