WebFrom the Table of Elements, we can see that mercury's atomic number is 80 and its atomic mass is 200.59. We'll need these numbers to get the information you want. The atomic number is the number of protons in an atom's nucleus, so we can tell right away that an atom of mercury contains 80 protons. Atoms, by definition, are electrically neutral. WebQuestion. The atomic number of a sodium atom is 11 and its mass number is 23. Calculate the number of protons, neutrons and electrons it contains.
