The Elements

I want to show you an example of a list of elements from the Periodic Table. The atomic mass represents how many neutrons are in each element. A.No(after each element) stands for the 'atomic number'of the element.The A.No represents the number of protons in the element. Hydrogen:A.No=1:A.Mass=1 Helium:A.No=2:A.Mass=4 Lithium: A.No=3:A.Mass=6.941 Beryllium:A.No=4:A.Mass=9 Boron: A.No=5:A.Mass=11 Carbon:A.No=6:A.Mass=12.001 Nitrogen:A.No=7:A.Mass=14 Oxygen:A.No=8:A.Mass=16 Fluorine:A.No=9:A.Mass=19 Neon:A.No=10:A.Mass=20 Sodium:A.No=11:A.Mass=22.990 Magnesium:A.No=12:A.Mass=24 Aluminium:A.No=13:A.Mass=27 Silicon:A.No=14:A.Mass=28 Phosphorus:A.No=15:A.Mass=31 Sulfur:A.No=16:A.Mass=32 Chlorine:A.No=17:A.Mass=35.5 Argon:A.No=18:A.Mass=40 Potassium:A.No=19:A.Mass=39.098 Calcium:A.No=20:A.Mass=40 Scandium:A.No=21:A.Mass=45 Titanium:A.No=22:A.Mass=48 Vanadium:A.No=23:A.Mass=51 Tomchem xxxxxxxxxxxxxxxxxx
