The order in the first attempt in the Periodic Table was in the increasing order of atomic weights of atoms. This gave 2 different places for isotopes of the same element with same properties and the same place for isobars with different properties. This was so because chemical properties of an element depends on its number of electrons which is basically given by the atomic number and not atomic weight. Again the lanthanides and actinides had different places inspite of having similar properties due to same atomic number.

What was the first attempt of listing elements on the periodic table?
The first attempt at listing elements on the periodic table was made by Dmitri Mendeleev in 1869. He arranged the elements in order of increasing atomic weight and grouped elements with similar properties together. Mendeleev's periodic table laid the foundation for the modern periodic table used today.
How is the periodic table is organized into columns called?
The elements arranged according to their atomic number in the table are called periodic table.
What characteristic was used to organize the first periodic table?
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
What are the order of elements on the periodic table based on?
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
How were the elements in the periodic table arranged?
By Atomic Mass

How did Amitri Mendeleev develop the First periodic table?
he developed the first periodic table in the increasing order of atomic masses of elements.but after the discovery of isotopesthis periodic table was not consider to be effective.
Why is hydrogen placed first in the periodic table?
Because It has 1 proton. The elements on the periodic table are order by the number of protons.
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 are the different features of periodic table?
- the periodic table is organized in periods and groups- chemical elements are listed in the order of the atomic number- the periodic table obey the law of periodicity

Did an English scientist create the first periodic table of elements?
No, the first periodic table of elements was created by the Russian chemist Dmitri Mendeleev in 1869. Mendeleev arranged the elements in order of increasing atomic mass and noticed a periodic pattern in their properties, which led to the development of the modern periodic table.
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.
He prepared the first periodic table of elements arranged in the order of atomic masses?
Dmitri Ivanovich Mendeleev
Who was the first scientist known to organize elements in order of their increasing mass?
Mendeleev from Russia was the first person to organize the periodic table of the elements
