Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.
What else can I help you with?
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.
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.
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.
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table
What does mendeleevs first periodic table look like?
The first periodic table was a handwritten table by Mendeleev. It had groups horizontally across the top and periods down the left hand side. The elements were all put into certain groups with only their chemicals symbols and atomic numbers depicted.
What was the problem with Mendeleevs table?
He left too many spaces between the elements......
What value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new elements
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 was the table arranged?
The Periodic Table was arranged by atomic number.
Was Mendeleevs table a completely regular grid?
not if u mean completely filled in but square by square yes
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.
