To which is the atomic mass equal

WebJul 21, 2024 · Mass number = Number of protons + Number of neutrons. One atom of sodium, for example, contains 12 neutrons and 11 protons, therefore the mass number of sodium is 11+12=23. Similarly, because a carbon atom contains 6 protons and 6 neutrons, its mass number is 6+6=12. A hydrogen atom has one proton but no neutrons. WebThe atomic number of calcium is 20. This number means that calcium has 20 protons. The atomic mass of calcium is 40. How many neutrons does calcium have? (Remember: protons + neutrons = atomic mass.) 2. Helium has an atomic number of 2. This number also means that helium has 2 protons. The atomic mass of helium is 4.
