WebThe radius of an atom must be defined arbitrarily, such as the boundary in which the electron can be found with 95% probability. Atomic radii are typically 30-300 pm. Figure … WebFig. 2: Carbon. 6 → Atomic number. 12 → Mass number. The atomic number, Z, gives the number of protons in the atom and therefore tells you which element the atom belongs to. The mass number, A, gives the combined total number of protons and neutrons in the atom.Therefore, you can find the number of neutrons by subtracting A from Z. In an …
