Protons in carbon 14 dating
The stable isotopes of silicon are: 28Si (the most abundant isotope, at 92.23%) (Neutrons 14) 29Si (4.67%) (Neutrons 15) 30Si (3.1%) (Neutrons 16) The Radioactive… It always has 40 protons and 40 electrons but the number of Neutrons varies depending on the isotope thus:- 88Zr unstable (48 neutrons) 89Zr unstable (49 neutrons) 90Zr stable (50 neutrons) 91Zr stable (51 neutrons) 92Zr stable (52 neutrons) 93Zr unstable (53 neutrons) 96Zr unstable (56 neutrons) There are 30 protons and 35 neutrons. 64Zn has 34 neutrons 65Zn has 35 neutrons and is synthetic 66Zn has 36 neutrons 67Zn has 37 neutrons 68Zn has 38 neutrons 70Zn has 40 neutrons 72Zn has 42 neutrons and is synthetic The number of neutrons is the difference between the mass number of an isotope and the number of protons.And of course each isotope has another number of neutrons.The mass of a neutron is almost identical to the mass of a proton.The number of neutrons determines which isotope of an…during his tenure as a professor at the University of Chicago.
The number of protons determines what element an atom is.Silicon has 14 protons and 14 electrons, however Silicon has numerous known isotopes with mass numbers ranging from 22 to 44.These isotopes are caused by silicon having differing numbers of neutrons in its nucleus. There is therefore no single answer to your question. There are a total of seven zinc isotopes, five of which occur naturally and two that are synthesized.The resulting neutrons ( but attempts to measure the production rate directly in situ were not very successful.Production rates vary because of changes to the cosmic ray flux caused by the heliospheric modulation (solar wind and solar magnetic field), and due to variations in the Earth's magnetic field.
