Question

Problem Silicon (Si) is a major component of semiconductor chips. 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).

mass number is the sum of protons and neutrons, the number of neutrons (N) equals
the mass number minus the atomic number:
Number of neutrons = mass number - atomic number, or N= A – Z (2.2)
