How could the modern periodic table remove various anomalies of mendeleevs periodic table?
1.) The Atomic Mass in Mendeleev's Periodic Table does not increase regularly. therefore, it was impossible to predict the number of elements between two elements.
The Modern Periodic Table has been made according to the increasing atomic number (Modern Periodic Law states that 'The properties of an element are the periodic function of its atomic number). The atomic number gives us the number of protons in the nucleus of an atom. the atomic number increases by one as we go from one element to the next. thus, this makes it easy to ascertain how many undiscovered elements may be there between two known elements.
2.) Mendeleev's periodic table was made according to increasing atomic masses. we know that of an element have same chemical properties and atomic number, but different atomic masses. So, the concept of isotopes can not be satisfied.
The Modern periodic table is according to increasing atomic numbers. Therefore, the problem of isotopes is easily dealt with.

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.
What was Mendeleevs proposal?
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
How periodic law leads the foundation of modern periodic table?
modern periodic law
Why is mendeleevs periodic table a model?
Mendeleev's periodic table is considered a model because it organizes elements based on their atomic mass and chemical properties, highlighting periodic trends and relationships among them. This arrangement allowed Mendeleev to predict the existence and properties of undiscovered elements, demonstrating the table's utility in understanding elemental behavior. Additionally, the structure of the table reflects the periodic law, which states that the properties of elements are a periodic function of their atomic mass. Thus, it serves as a foundational framework for modern chemistry, despite later modifications based on atomic number.
How many rows are there in Modern periodic table?
There are 7 periods in the modern periodic table.
How many periods are there on the modern periodic table?
The modern periodic table has seven periods.
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.
What did Mendeleevs periodic table look like?
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.
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.
Is The modern periodic table is organized by atomic number?
Yes.The modern periodic table is organized by atomic number. The elements properties are found to be periodic.
