View the periodic table as starting at the top left and ending at the end of the last row, near the bottom right. The table is structured from left to right in order of increasing atomic number. The atomic number is the number of protons in a single atom.
Not every row or column is complete. Although there may be breaks in the center, reading the table will continue from left to right. For instance, Hydrogen has an atomic number of 1 and it is in the top left. Helium has an atomic number of 2 and it is in the top right.
Elements 57 through 102 are usually pictured as a subset at the bottom right of the table. These are the “rare earth elements.”
