The greatest triumph of Mendeleev's periodic table was his predictions of the existence of the undiscovered elements.

Dmitri Mendeleev's greatest triumph with the Periodic Table was his ability to predict the properties of undiscovered elements. Gaps in the table led him to propose the existence of new elements with specific characteristics, which were later discovered and matched his predictions, confirming the validity of his periodic law.

Mendeleevs periodic table of elements was created in 1901?
Actually, Dmitri Mendeleev formulated the periodic law and published his periodic table of elements in 1869. This table arranged elements by increasing atomic mass and grouped them based on similar properties, predicting the properties of missing elements. It was a significant contribution to the field of chemistry.
What was Mendeleevs proposal?
Mendeleev proposed the periodic law and created the first periodic table of elements. He organized the elements based on their atomic mass and chemical properties, predicting the properties of undiscovered elements. His work laid the foundation for the modern periodic table used today.
What did Mendeleevs periodic table look like?
Mendeleev's periodic table consisted of rows and columns organizing elements based on their atomic mass and chemical properties. Gaps were left for undiscovered elements, which Mendeleev predicted and named. His table laid the foundation for the modern periodic table we use today.
Why did scientists try to improve Mendeleevs table?
Scientists tried to improve Mendeleev's periodic table to account for the discovery of new elements, better organize elements based on their properties, and to address inconsistencies in the original table. This led to the development of the modern periodic table with elements arranged in increasing atomic number and grouped based on similarities in chemical properties.
Which element in period 5 of the periodic table has the greatest number of protons?
Element 92, uranium, has the greatest number of protons in period 5 of the periodic table.
How was mendeleevs periodic table like todays periodic table?
it has elements
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table
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 were mendeleevs discoveries and predictions and discoveries abot the periodic table?
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
What changes were made to the periodic table after Dmitri mendeleevs discovery?
they changed the 3 new Elements.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
Which two elements on the periodic tabel would have been placed in different groups in moseleys periodic table but not in mendeleevs?
bi and po
Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.

What is the greatest contribution of periodic table in chemistry?
In chemistry all most all elements properties are known based on periodic table.
What element on the periodic table has the greatest metallic properties?
iron
