Mendeleev's Periodic Table helped scientists better understand elements by arranging them in order of increasing Atomic Mass and grouping elements with similar properties together. This organization highlighted patterns and trends in element properties, leading to the prediction of missing elements and their properties. Through this framework, scientists were able to make connections between elements and lay the groundwork for further advancements in chemistry.

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.
What is the significance of the periodic table in understanding the groupings and properties of elements?
The periodic table is significant because it organizes elements based on their properties and groupings. This organization helps scientists understand the relationships between elements and predict their behaviors.
Why does the periodic table split into different sections?
The periodic table splits into different sections based on the properties of the elements. Elements are grouped together if they have similar characteristics, such as reactivity or electron configuration. This organization helps scientists understand and predict the behavior of different elements.
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.
How could you use Mendeleevs periodic table to identitify new elements?
Mendeleev's periodic table can be used to predict the properties of unknown elements based on their position in the table in relation to known elements. Gaps in the periodic table can suggest the possibility of unknown elements with specific properties, guiding scientists in their search for new elements that fit those predicted properties. By applying Mendeleev's periodic law, researchers can make educated guesses about the characteristics of undiscovered elements and tailor their experimental efforts accordingly.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table
What changes were made to the periodic table after Dmitri mendeleevs discovery?
they changed the 3 new 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
What do elements in the periodic table do?
The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.
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.
Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
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.
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.

What is one way scientists have grouped elements?
the Periodic Table of elements
Why does the periodic table split into different sections?
The periodic table splits into different sections based on the properties of the elements. Elements are grouped together if they have similar characteristics, such as reactivity or electron configuration. This organization helps scientists understand and predict the behavior of different elements.
