Dmitri Mendeleev was the scientist who arranged the periodic table according to the element's Atomic Mass. Later on, he then arranged it according to the element's Atomic Number.
periodic table
In 1869, a Russian scientist named Dmitri Mendeleev arranged the elements in a table according to their atomic mass, this was the first periodic table. However, a few elements didn't fit the pattern in Mendeleev's table, so a new table had to be made, and that table is today's periodic table which is arranged by atomic number, and not atomic mass.
Henry Moseley established atomic number as basis of periodic table.The properties of elements are periodic function of their atomic number.
The elements on the periodic table are arranged in order of increasing atomic number.
atomic number
That would be Mendelevium, of atomic number 101. Named after Dmitri Mendeleev.
periodic table
The Periodic Table of Elements was modified by the English scientist Henry Moseley in the year 1913. Moseley assessed the atomic number of the elements individually and organized the atoms according to increasing atomic number.
A Russian scientist name, Dmitri Mendelee in 1869, is given credit for inventing the Periodic Table. Although, he did base his research on a French scientist name, Antoine Lavoisier. The reason why Mendelee invented the Periodic Table was to create a why to logically organized the known elements by their atomic weight, atomic mass, and atomic number.
The periodic table is a function of the atomic number.
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
In modern periodic table, elements are listed by increasing atomic number.

Henry Moseley established atomic number as basis of periodic table.The properties of elements are periodic function of their atomic number.
The large number on the periodic table is the atomic number. There is a smaller number that is the atomic weight. For example, Titanium's atomic number is 22 and its atomic weight is 47.867.
the atomic number is the number of protons in a certain element. elements are arranged on the periodic table by atomic number in increasing order
The atomic number of each element is on the periodic table. The elements are arranged on the periodic table in order of increasing atomic number.
