Mendeleev ordered the elements according to increasing atomic mass in vertical and horizontal rows. The horizontal rows contained analogous elements. This system was clear and consistent, and was superior because the number of protons, the most massive particle in atoms, is actually what distinguishes each element.
What else can I help you with?
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.
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.
Who created the first acceptable periodic table?
Dmitri Mendeleev is credited with creating the first widely accepted periodic table of elements in 1869. He arranged the elements according to their atomic mass and properties, predicting the properties of missing elements and leaving gaps for future discoveries.
What made mendeleevs periodic table particularly special?
Mendeleev's periodic table was particularly special because it organized elements based on atomic mass and their chemical properties, revealing a periodicity that highlighted the relationships between them. He left gaps for undiscovered elements, predicting their properties, which demonstrated the table's utility and foresight. His work laid the foundation for the modern periodic table, emphasizing the importance of atomic structure and periodic trends in chemistry.
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table
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 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 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
Which two elements on the periodic tabel would have been placed in different groups in moseleys periodic table but not in mendeleevs?

Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
Who is considered to be the father of the periodic table?
Dmitri Mendeleev is considered the father of the periodic table. He created the first widely accepted version of the periodic table in 1869, arranging elements based on their properties and atomic weights. Mendeleev's table laid the groundwork for the modern 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.
Which version of the periodic table do you use now?
The modern long form version of the periodic table is now accepted by the IUPAC.
Why was Mendeleev's periodic table accepted by most chemists?
Mendeleev's periodic table was accepted because it accurately predicted the properties of unknown elements and left spaces for them, demonstrated the periodicity of elements based on atomic mass, and was flexible enough to accommodate newly discovered elements. Its predictive power and organization of elements based on their physical and chemical properties made it successful and widely accepted.
Who created the first acceptable periodic table?
Dmitri Mendeleev is credited with creating the first widely accepted periodic table of elements in 1869. He arranged the elements according to their atomic mass and properties, predicting the properties of missing elements and leaving gaps for future discoveries.
