Presumably because atomic number is the fundamental characteristic for organizing the Periodic Table itself. Every element in the interior of a period of the periodic table has an atomic number greater by 1 than its neighbor to the left and less by 1 than its neighbor to the right; every element (except hydrogen) at the left end of a periodic table period has an atomic number greater by one than the rightmost member of the preceding period; and every element at the right end of a periodic table periodic has an atomic number less by 1 than the leftmost element in the succeeding period, if such a succeeding period exists.

Is the atomic number of each element included in the periodic table?

YES!!! The atomic No. is the postition of the element in the periodic table. It also indicates the number of protons in the element and electrons in the neutral element. The Atomic Mass is also included in the periodic table. The Atomic Mass is the sum of all the protons and neutrons of an element in the periodic table. Here are some examples. Hydrogen ; [1/1]H The first element in the table Carbon ; [12/6]C The sixth element in the periodic table Oxygen ; [16/8]O The eighth element in the periodic table et.seq., The first number given is the Atomic Mass and the second number is the Atomic Number.
