Final answer:

The correct number of protons, neutrons, and electrons for 35Cl-1 is 17 protons, 18 neutrons, and 17 electrons.

Step-by-step explanation:

The correct number of protons, neutrons, and electrons for 35Cl-1 is:

  • 17 protons
  • 18 neutrons
  • 17 electrons

Chlorine has an atomic number of 17, which corresponds to the number of protons and electrons it has. The isotope of chlorine with a mass number of 35 has an extra neutron, making a total of 18 neutrons.

Final answer:

The ion 35Cl- has 17 protons, 18 neutrons, and 18 electrons, with the additional electron accounting for the negative charge of the ion.

Step-by-step explanation:

Correct Number of Protons, Neutrons, and Electrons for 35Cl-

The isotope in question is marked as 35Cl-. This notation indicates that the element is chlorine (Cl) and its mass number (which is the sum of protons and neutrons) is 35. The negative sign (-) signifies that it has an extra electron, giving it a negative charge. Chlorine has an atomic number of 17; hence, it has 17 protons. To find the number of neutrons, we subtract the atomic number from the mass number: 35 - 17 = 18 neutrons. Since the ion is negatively charged (specifically with a charge of -1), it must have one more electron than protons, totaling 18 electrons. Therefore, a chlorine ion with a mass number of 35 and a -1 charge has 17 protons, 18 neutrons, and 18 electrons.
