Oct 22, 2007 · An isotope is a compound with the same number of protons and electrons, but different number of neutrons. The three most natural isotopes of Mg are Mg-24, Mg-25, and Mg-26. Mg-24 (12 neurtrons) is 78.9%, Mg-25 (13 neutrons) is 10% and Mg-26 (14 neutrons) is 11.01%, of all the Magnesium found in nature. By just looking at the atomic number, right off the bat we know that the number of protons is the same as the atomic number. For example, in the element Iodine, the atomic number is 53, so that way we know that there are 53 protons. Then, we could assume that the number of the protons and the numbers of the electrons are equivalent.
