Russian chemist Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by Atomic Mass. He predicted the discovery of other elements, and left spaces open in his periodic table for them.
Dmitri Mendeleev is credited with arranging the Periodic Table based on atomic masses. He organized the elements with similar properties into columns known as groups or families, laying the foundation for the modern periodic table we use today.

How are the elements in the first periodic table arranged?
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
How did Mendeleev arrange chemical elements?
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
What trends were seen in Mendeleev's periodic table?
he arranged his Periodic Table by each elements Atomic Mass
State the periodic law on which Mendeleev's Periodic table was based and why and how this periodic law changed?
Mendeleev's Periodic Table was based on the periodic law which states that the properties of elements are a periodic function of their atomic masses. This law changed with the discovery of atomic number by Moseley which stated that the properties of elements are a periodic function of their atomic numbers, leading to a more accurate and modern periodic table based on atomic number.
How does mendeleevs periodic table differ from moselys periodic table?
Mendeleev's Periodic Table was different from Moseley's in that Mendeleev arranged the elements inÊthe table according to atomic masses while Mosley's periodic table was arranged accordingÊto atomic numbers that were increasing.ÊÊThe modern periodic table used today is based on the Moseley model.
Who discover the old Periodic Table?
Mendeleev discovered old periodic table. He arranged elements in order of atomic masses.
How were the elements arranged in the spiral periodic table?
in order of their reletive atomic masses
Who was or is Mendeleev in periodic tables?
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
What are some ways that elements are arranged on the periodic table of elements?
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
How did mandeleev arranged chemical elements?
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
Why is mandeevel's periodic table no longer valid?
Mendeleev's table was arranged according to increasing atomic masses , which had certain drawbacks. Now, modern periodic table is arranged in order of increasing atomic number.
Main idea of mendeleevs first periodic table?
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
What did Dmitri invented in 1869 for the periodic table?
Dmitri invented a periodic table in 1869 where he arranged the elements in order of increasing atomic masses.
What method did Dmitri use to organize the elements of the periodic table?
Dmitiri Mendeleev arranged the Periodic Table of elements in order of increasing atomic masses.
How are the elements in the first periodic table arranged?
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
How was mendeleev period table arranged?
Mendeleev arranged the elements are arranged in order of increasing atomic masses. He founded that properties of elements are periodic when arranged in this pattern.
What was Mendeleev's periodic table was organized by?
Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.
