[1 mark] Criticality may only be achved with a water moderator if the fuel is enriched. Enrichment increases the proportion of the fissile isotope U-235 about five- to seven-fold from the 0.7% of U-235 found in natural uranium. Enrichment usually relies on the small mass difference between atoms of the two isotopes U-238 and U-235.

Each nuclide is denoted by chemical symbol of the element (this specifies Z) with tha atomic mass number as supescript. Therefore, we cannot determine the neutron number of uranium, for example. We can determine the neutron number of certain isotope. For example, the neutron number of uranium-238 is 238-92=146. Chemists often use the names parent isotope and daughter isotope to represent the original atom and the product other than the alpha particle. In the previous example, U 92 235 is the parent isotope, and T 90 231 h is the daughter isotope. When one element changes into another in this manner, it undergoes radioactive decay. The most prominent form of hydrogen is protium, 0.0156% of hydrogen is present on the earth’s surface as deuterium. In tritium, the concentration is one atom per 1018 atoms of protium. Out of these three isotopes of hydrogen, Out of these three isotopes of hydrogen, the only tritium is radioactive in nature which emits low energy b particles.

The chemical symbol for Uranium is U. Uranium is a silvery-white metal in the actinide series of the periodic table. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. Uranium has the highest atomic weight of the primordially occurring elements.

Csgo unblockedSo I could write a big S. Now, the next thing we might want to think about is the mass number of this particular isotope. Remember, an isotope, all sulfur atoms are going to have 16 protons, but they might have different numbers of neutrons. So, the sulfurs that have different number of neutrons, those would be different isotopes. Write the symbol for each isotope in the form A Z X. and Express your answer as an isotope.
