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.
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......
How many elememnts are in the periodic table?
There are either 118 or 117 elements in the peiodic table. it depends on the one that you are looking at.
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.

How did later chemists change Mendeleevs periodic table?
They used atomic number instead of Atomic Mass to organize the elements
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table

How many noble gases are listed on the peiodic table?
six. helium, neon, argon, krypton, xenon, radon
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
How did chemist change mendeleevs perioic table in the early 1900s?
Chemists in the early 1900s made changes to Mendeleev's periodic table by rearranging elements based on their atomic number instead of atomic mass, leading to the development of the modern periodic table. This change accurately emphasized the relationship between an element's properties and its atomic number, rather than its atomic mass, and helped to better organize the elements.
Was Mendeleevs table a completely regular grid?
not if u mean completely filled in but square by square yes
