In the most common isotope of silicon, there are 14 neutrons.
that's easy....it's 24 neutrons....cuz it's 45(the atomic mass) - 21 ( the # of protons/ atomic number)
117
someone really needs to answer this question. i am going to flunk this project if i dont know this. PLEASE WHOEVER IS OUT THERE ANSWER NOW!!
Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of iron is 26;
