It has three naturally occurring isotopes: 28Si, 29Si, and 30Si. Determine the numbers of protons, neutrons, and electrons in each silicon isotope.Plan The mass number (A; left superscript) of each of the three isotopes is given, which is the sum of protons and neutrons. From the elements list on this book’s inside front cover, we find the atomic number (Z, number of protons), which equals the number of electrons. We obtain the number of neutrons by subtracting Z from A (as shown).
