Answer 1

If you know an element's atomic number and atomic mass, you can determine:

• The number of protons: The atomic number is equal to the number of protons in an atom of the element.
• The number of neutrons: You can calculate the number of neutrons by subtracting the atomic number from the atomic mass (rounded to the nearest whole number).

So, the best choice that includes all relevant information is:

the number of protons and neutrons
