Last week, I learned about atoms. Two days ago, I learned about the periodic table. I learned that in an element a periodic table has the element name, how many atoms there are and it’s atomic weight. For example, above is gold. In the top left, the number 79 is how many atoms gold has. The number of atoms determine the element. The words in the middle are golds name. Au is it’s name on the periodic table of elements. Finally the number on the bottom, 196.97 is the atomic weight.
