The modern Periodic Table does a lot of things. It organizes elements in order of electron orbitals for one thing (1s, 2s, 2p, 3s, 3p, 4s, ect..). It also has all noble gases stacked on top of each other helping to determine the columns of 1-8 valence electrons. It seperates all metals from nonmetals and elements in the same column will have similar physical and chemical properties.
The order is based on the number of protons an atom of that element has in its nucleus.
The periodic table of the elements is organized by the simularities between each of the elements.
The order of the elements in the periodic table are based on increasing atomic number. The atomic number is the number of protons in the nucleus of an atom in any given element.

Number of protons in the nucleus.
the elements in the modern periodic table are arranged according to their increasing atomic number.
The two tables were virtually identical. However, because he drafted his table earlier in 1869 and because his table included "blanks" for yet-to-be-discovered elements to fit, Mendeleev is given the major recognition for the organization of the elements.

There are 7 periods in the modern periodic table.
The modern periodic table has seven periods.
Modern periodic table is invented by Henry Moseley.
The present periodic table is arranged in order of increasing atomic numbers not the atomic weights , before modern periodic law the elements were arranged on the basis of atomic weights.
Periodic table of elements.
Modern periodic table is based on modern periodic law which states that physical and chemical properties of elemnts are periodic function of their atomic numbers.
