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 else can I help you with?
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
How was mendeleevs periodic table like todays periodic table?
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
What did mendeleev do with the three black spaces he had on his table?
In his periodic table, Dmitri Mendeleev left three blank spaces for elements that had not yet been discovered. He predicted the properties of these elements based on their position in the table, suggesting that they would fit into the framework he established. Mendeleev's foresight was validated when subsequent discoveries, such as gallium, scandium, and germanium, matched his predictions, reinforcing the validity of his periodic law.
What made mendeleevs periodic table particularly special?
Mendeleev's periodic table was particularly special because it organized elements based on atomic mass and their chemical properties, revealing a periodicity that highlighted the relationships between them. He left gaps for undiscovered elements, predicting their properties, which demonstrated the table's utility and foresight. His work laid the foundation for the modern periodic table, emphasizing the importance of atomic structure and periodic trends in chemistry.
What was the name predicted for gallium by mendeleevs?
Mendeleev predicted the name "eka-aluminium" for the element that is now known as gallium. This naming convention was based on the positions of the elements in his periodic table.
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.
Were Meneleev's predictions correct?
If you mean his predictions about the periodic table then yes his predictions were correct.
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?

Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
What are Dmitri Mendeleev's discoveries except the periodic table are?
Periodic Principles Law of Periodicity Periodic Table of Toxic Elements These are three of the many discoveries Dmitri Mendeleev researched during his life (1834-1907).
How was mendeleevs periodic table like todays periodic table?
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
What is the greatest triumph about mendeleev's periodic table?
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.
Why were Mendeleevs efforts on the peridic table more successfully the other scientist?
Mendeleev's table was more systematic. Elements were arranged in order of atomic masses.
