Long dashes in the Mendellev's periodic table represent the element which were not discovered yet and these elements were discovered later on.
The answer is: Au
Actually, Dmitri Mendeleev formulated the periodic law and published his periodic table of elements in 1869. This table arranged elements by increasing atomic mass and grouped them based on similar properties, predicting the properties of missing elements. It was a significant contribution to the field of chemistry.
The letter "J" is not used to represent any elements in the periodic table.
Some common questions about the periodic table include: What is the periodic table? How is it organized? What do the numbers and letters on the table represent? Why are some elements grouped together? How many elements are there in total?
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.
To understand the concept of Periodic Table
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
they changed the 3 new Elements.

No. they dont represent the periodic table.
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.

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.
The answer is: Au
