How is the periodic table organize?
The current Periodic Table is organized by each elements atomic number. The atomic number is the number of protons in the nucleus of the atom of each element.
How is the current periodic table of the elements organized?
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
