JJ Thomson discovered the electron in 1897.
This scientist was J. J. Thomson.
De Chancourtois is known for his contribution to the development of the early periodic table of elements. He arranged the elements in a spiral or helical format based on atomic weights, which foreshadowed the modern periodic table structure. This arrangement helped in understanding the periodic trends and relationships between elements, paving the way for the organization of elements we use today.
He found the number of protons an element has. present periodic table is according to it.
Dmitri Mendeleev is credited with creating the periodic table of elements. He organized elements by their atomic mass and properties, which led to the development of the modern periodic table.
Mosley arranged elements in order of increasing atomic number
This scientist was J. J. Thomson.
Henry Moseley showed elements in the periodic table should be in order by their atomic number instead of atomic mass.
Julius Lothar Meyer played a significant role in the development of the periodic table by independently publishing a periodic table of elements that showed the correlation between atomic volume and atomic weight. His work helped pave the way for the later development of the modern periodic table based on atomic number. Meyer's contribution, along with that of Dmitri Mendeleev, laid the foundation for our current understanding of the organization of elements.

he invented the first periodic table..
In chemistry all most all elements properties are known based on periodic table.
Early scientists like Dmitri Mendeleev and Julius Lothar Meyer made contributions to the development of the periodic table by arranging elements based on their properties and atomic masses. Mendeleev's work led to the creation of the modern periodic table, which helped predict the properties of undiscovered elements and organize known elements in a systematic way. Meyer also made significant contributions by independently arranging elements in a periodic manner, which further supported the development of the periodic table.
He helped with the periodic table of elemnts.
Dobereiner, Newland , Mendeleev are responsible for development. Modern periodic table was created by Henry Moseley.
periodic table allows you to determine weather or not the elements will conduct electrocoty
Dmitri Mendeleev's major contribution was the development of the periodic table of elements. This organization of elements based on their atomic number and properties revolutionized chemistry and laid the foundation for modern chemistry and physics. His work has had a profound impact on scientific understanding and continues to influence research and education today.
He found the number of protons an element has. present periodic table is according to it.
