Final answer:
The atomic number of a sulfur atom with 16 protons is 16, and the atomic mass number is the sum of the protons and neutrons, which totals 32.
Step-by-step explanation:
A sulfur atom with 16 protons and 16 neutrons will have an atomic number of 16 and an atomic mass number of 32. The atomic number, which is the number of protons in an atom's nucleus, defines the chemical element. In this case, sulfur has the atomic number 16, denoted as 'S' on the periodic table.
The atomic mass number is the sum of the number of protons and neutrons in the nucleus. So for sulfur with 16 protons and 16 neutrons, the atomic mass number is 16 + 16, which equals 32. The atomic number of an element is equal to the number of protons it has in its nucleus.
In this case, the sulphur atom contains 16 protons, so its atomic number is 16. The mass number of an element is equal to the sum of the number of protons and neutrons in its nucleus. Since the sulphur atom contains 16 protons and 16 neutrons, its mass number is 16 + 16, or 32.
