Quizplus · Accepted Answer

The atomic number of titanium (Ti) is 22, therefore an atom of 11ea7e31_c150_da95_9bba_fb48fbd8cb81_TB4943_11Ti has 22 protons. The atomic mass of this isotope (11ea7e31_c150_da95_9bba_fb48fbd8cb81_TB4943_11Ti) is 43, which is the sum of the protons and the neutrons. Therefore, the number of neutrons is (atomic mass - atomic number) = 43 - 22 = 21. Hence, the correct answer is option C.
