From the Periodic Table... WebThe atomic number of an atom is determined by the total number of protons in its nucleus. The letter 'Z' is used to signify it. Example: The atomic number of iron is 26 because an atom of iron has 26 protons in its nucleus. A given element's atoms all have the same number of protons, and thus the same atomic number. Atomic Number of F e

WebApr 11, 2024 · The 1s electron of the iron (which is the closest one to the nucleus) sees an effective atomic number theory (which is the number of protons) of 25. The reason behind why it is not 26 is due to some of the electrons present in the atom end up repelling the others by giving a nucleus' net lower electrostatic interaction. WebMass Number = # of Protons + # of Neutrons. Mass Number = 1 + 2. Therefore, this particular atom of hydrogen will have a mass number of 3. Note that the mass number calculated in Example 2.4. 1 does not match the number underneath the elemental symbol and name for hydrogen on the periodic table. simply southern slippers
