Each element on the Periodic Table has two numbers: the atomic number and the relative Atomic Mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.

Why is hydrogen on the top of modern periodic table?
The periodic table is arranged by atomic mass. Hydrogen is the lightest element. Its atomic mass is one.
How are atomic mass on the periodic table calculated?
Atomic mass is determined by mass spectrometry.
How do you find the atomic mass and the atomic number?
The atomic number is the whole # on the periodic table or the # of protons in an atom. The atomic mass is the # that is not the whole # on the periodic table, or you can multiply the mass of the isotope by its abundance and add the answers together.

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.
What is the difference between the periodic table and Mendeleev's table?
Mendeleev's table was arranged by atomic mass and the periodic table is arranged by protons (atomic number).
Is your modern periodic table based on atomic mass or atomic number?
The modern periodic table is arranged according to the elements' atomic numbers.
What does the atomic number and atomic mass have to do with the arrangement of the elements on the periodic table?
The elements on the periodic table are arranged in order of increasing atomic number.
