Answer:
The number of neutrons in one atom of sulfur with an atomic mass number of 34 is 18.
Explanation:
Each chemical element is characterized by the number of protons in its nucleus, which is called the atomic number Z. But in the nucleus of each element it is also possible to find neutrons, the number of which can vary. The atomic mass (A) is obtained by adding the number of protons and neutrons of a given nucleus. Then:
atomic number = number of neutrons + number of protons
By looking at a periodic table, you can see that the atomic number of sulfur is 16. Then this means that the mentioned element has 16 protons. And knowing that the atomic mass number of sulfur is 34, you can calculate the number of neutrons:
34= number of neutrons + 16
34 - 16= number of neutrons
18 = number of neutrons
The number of neutrons in one atom of sulfur with an atomic mass number of 34 is 18.
