it has been revised. also it is not organized anymore by atomic weight... it is organized by atomic number. Glenn Seaborg discovered the transuranic elements, from 94 to 102. one of the biggest changes was the whole new family of the noble gases.
firstly the fundamental basis of classification changed from Atomic Mass to atomic number secondly left up gaps were filled up
After Mendeleev's discovery of the Periodic Table, some changes were made to reflect new elements discovered and to account for inconsistencies. These changes included the addition of new elements, reorganization of elements based on atomic number instead of atomic weight, and the creation of the modern periodic table which is based on the electronic structure of atoms.

What value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new 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.
What changes may come that would change the periodic table?
Changes in the number of protons in an element's nucleus would alter its position on the periodic table. The discovery of new elements could lead to the expansion of the periodic table. Advances in technology and research may also reveal new properties of known elements, potentially causing revisions to the 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
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 changes were made to the periodic table after Dmitri mendeleevs discovery?
they changed the 3 new Elements.
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table
What changes were made on the periodic table of elements after Dmitri Mendeleev's discovery?
alot of changes

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 to the periodic table after Dmitri Mendeleev discovery?
they changed the 3 new 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.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements

Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
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.
