The modern periodic table is organized by the atoms atomic number as opposed to Mendeleev's periodic table which was organised by their atomic weight. The atomic number of an atom is the number of protons found in the nucleus of a certain atom.
well its organized by its atomic number and an atomic number for those of you who don't know this is the amount of protons and electrons an element has
The modern Long form periodic table is arranged according to increasing atomic number and repeating properties.

The modern periodic table is organized by atomic number.
By increasing atomic number
Atomic Number
In modern periodic table, elements are listed by increasing atomic number.
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
In the modern periodic table, the elements are arranged in order of increasing atomic number.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
Atomic Number (amount of protons)
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
The modern version of the periodic table is arranged according to the atomic number.
Atomic number
Elements are arranged in order of increasing atomic number in the modern periodic table.
The elements on the modern periodic table are arranged based on the increasing order of atomic number and repeating properties.
In modern periodic table, elements are listed by increasing atomic number.
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
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.
Modern periodic table comprises of elements arranged in order of increasing atomic number. It was created by Henry Moseley.
Niels Bohr: the modern periodic table where the elements are arranged in the increasing order of atomic number Mendeleev: The periodic table where the elements are arranged in the increasing order of atomic mass
the elements in the modern periodic table are arranged according to their increasing atomic number.
The modern periodic table is arranged in the increasing order of their atomic number and repeating properties.
