The Periodic Table is arranged by increasing atomic number, which is the number of protons in the atoms of that element. All elements of the same element have the same atomic number. Each element has a unique atomic number. The number of protons in the nucleus of an atom defines it as that particular atom.
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
Mendeleev arranged the known chemical elements in a table according to increasing atomic mass and similar chemical properties. This arrangement led to the periodic table of elements, where elements with similar properties fall into the same column or group. This organization allowed Mendeleev to predict the properties of undiscovered elements and leave spaces for them in the table.
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
Dimitri Mendeleev arranged the known chemical elements into a systematic chart known as the Periodic Table. By organizing the elements by atomic number and properties, this table allows for predictions of the behavior and characteristics of elements within each group.
Mendeleev arranged the elements in his periodic table in order of increasing atomic mass while also grouping elements with similar properties together. His periodic table laid the foundation for the modern periodic table we use today.
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
Dmitri mendeleev arranged elements in order of increasing atomic masses. He considered chemical properties of the elements, their oxides and nitrides.
Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.

Mendeleev's periodic table was similar to the modern periodic table in that both are organized by increasing atomic number and have elements grouped according to similar chemical properties. Additionally, both tables have blank spaces where undiscovered elements were predicted to exist.
Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Dmitri Mendeleev arranged the elements in his periodic table in order of increasing atomic mass and grouped elements with similar properties together. This arrangement helped him to identify periodic trends and predict the properties of undiscovered elements.
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
The periodic table was first arranged by Dmitri Mendeleev in 1869. He organized the elements by increasing atomic mass and grouped them based on similar chemical properties. Gaps were left for undiscovered elements, with their properties predicted based on neighboring elements.
