Why was Mendeleev's decision to leave blank spaces on his table sometime referred to as his most significant contribution to periodic table?
Mendeleev thought about the future and realized that it was entirely unlikely that all earthly elements had been discovered, so he left blank spaces in his table and even predicted some of the elements that would fit in those spaces. Surprisingly enough, as time passed, chemists began discovering many of the elements that he had predicted, which fit perfectly into his Periodic Table.
What else can I help you with?
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.
Julius Lothar Meyer its contribution to the development of the periodic table?
Julius Lothar Meyer played a significant role in the development of the periodic table by independently publishing a periodic table of elements that showed the correlation between atomic volume and atomic weight. His work helped pave the way for the later development of the modern periodic table based on atomic number. Meyer's contribution, along with that of Dmitri Mendeleev, laid the foundation for our current understanding of the organization of elements.
What was Mendeleevs proposal?
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
Describe the contribution of early scientist in the development of periodic table?
Early scientists like Dmitri Mendeleev and Julius Lothar Meyer made contributions to the development of the periodic table by arranging elements based on their properties and atomic masses. Mendeleev's work led to the creation of the modern periodic table, which helped predict the properties of undiscovered elements and organize known elements in a systematic way. Meyer also made significant contributions by independently arranging elements in a periodic manner, which further supported the development of the periodic table.
What did Mendeleevs periodic table look like?
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known 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.
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table
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
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 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
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.
Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
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.
What is the contribution of Dmitri mendeleev?
he invented the first periodic table..
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.
Contribution of Julius Loather Meyer?
He helped with the periodic table of elemnts.
