How many neutrons would there be in an atom of sulfur - 34?
A. 18
B. 8
C. 16
D. 10
C. 16
To find the number of neutrons in an atom, you need to subtract the atomic number from the mass number. The atomic number of sulfur is 16.
Therefore, the number of neutrons in an atom of sulfur-34 would be:
34 (mass number) - 16 (atomic number) = 18
So the answer is A. 18.
