Answer:

B. 16

Explanation:

Cl -35 and Cl-33 have the same number of protons because it is the same element Cl.

Their masses are different because they have different number of neutrons.

Cl- 33 has 2 neutrons less than Cl-35.

35 - 33 = 2

If Cl-35 has 18 neutrons, then Cl-33 has 18-2=16 neutrons.
