Iodine Half-Life Experiment. Iodine is element number 53. That is, Iodine has 53 protrons and 53 electrons. That is what determines that it is Iodine. We could also say that for Iodine, Z = 53. How many neutrons does Iodine have? Most naturally-occuring Iodine is Iodine-127. We could say A = 127. Remember, A is the atomic mass number of an isotope -- the total number of nucleons inside the nucleus. A is the total number of the protons and neutrons inside the nucleus, A = Z + N. N = A - Z. N = 127 - 53. N = 74. Most naturally-occuring Iodine has 74 neutrons. We can write this as. 127 I 53. What happens if this naturally-occuring Iodine-127 absorbs a neutron?
Best Answer: you are correct that protons determine the element's identity. Mg-24 and Mg-26 both have 12 protons but the 24 and 26 are the number of protons plus neutrons. Mg-24 has 12 protons and 12 neutrons, while Mg-26 has 12 protons and 14 neutrons. elements that have the same number of protons but different numbers of neutrons are called isotopes. Mg will always have 12 protons...if you change the number of protons, you change the element. Mg-24 and Mg-26 are two different isotopes of magnesium.
