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 value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new elements
What was the problem with Mendeleevs table?
He left too many spaces between the 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 was the importance of Mendeleevs periodic table to chemists?
In Mendeleev's period table, the elements were arranged by both weight and valence. Mendeleev noticed certain elements were very close in weight and properties and hypothesized other elements that would lie between them. These were the basis of groups. He also noticed weights increased regularly and formed these into periods.

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.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
Was Mendeleevs table a completely regular grid?
not if u mean completely filled in but square by square yes
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.
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.
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.
How does the periodic table makes life easier?
The periodic table organizes all known elements based on their properties, making it easier for scientists to understand and predict their behavior. This organization helps chemists identify patterns and trends in element behavior, leading to important discoveries and advancements in various fields, from medicine to materials science.
