Isotope Practice 1. Here are three isotopes of an element: 12C 14 13C C a. The element is: Carbon b. The number 6 refers to the Atomic Number c. The numbers 12, 13, and 14 refer to the Mass Number d. How many protons and neutrons are in the first isotope? 6 protons & 6 neutrons e. How many protons and neutrons are in the second isotope?
A common way of writing the name of an isotope is to put the mass number after the name, For the isotopes above the names would be; Carbon-12, Carbon-13 and Carbon-14. Use this knowledge to complete the following chart.

Carbon-14: Also known as radiocarbon or 14C, this radioactive carbon isotope contains eight neutrons, or two more than 12C, the most common form of carbon. Over time, 14C decays into N (along with an electron and antineutrino), so the relative amount of 14C remaining in an artefact reveals its age. Cosmic rays: High-energy particles that move ...
