Web28 feb. 2024 · The atomic weight values may be different from one periodic table to another because it's a calculated number, based on the weighted average of the natural isotopes of an element. If a new supply of an element is discovered, the isotope ratio may be different from what scientists previously believed. WebThe atomic number is the number of protons in an atom of an element. In our example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus. The interesting thing here is that every atom of krypton contains 36 protons. If an atom doesn't have 36 protons, it can't be an atom of krypton.
