It all started with the discovery of individual elements like gold, silver, copper. The discovery of the number of elements increases, therefore the scientists classified the elements on the basis of their properties in the periodic table.
The Periodic Table was developed by Dmitry Mendeleev in 1869. He organized the known elements based on their chemical properties and atomic weights, placing elements with similar properties in the same vertical columns. Mendeleev's periodic table provided a structure and system to understand and predict the behavior of elements, and it has since been expanded and refined as new elements have been discovered.
All of them, the periodic table has all of the elements the human discovered or made..
Moseley discovered modern periodic table. It was not given by Bohr.
He could predict other elements because there was an obvious gap, but he couldn't predict the noble gases because he didn't realize that there was going to be an 18th group since none of them were yet discovered. When he first started organizing the periodic table, the pattern still made sense even without the noble gases.
No.

Dmitri Mendeleev made the periodic table. He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
Moseley discovered the modern periodic table.
Demitri Mendeleev discovered a pattern to the periodic table in 1869.

The periodic table was first proposed by a Russian chemist Dimitri Mendeleev. The modern periodic table ordered by atomic number was proposed by an English physicist, Henry Moseley.
No.
The periodic table of the elements is not a physical table, it is a concept. It is made out of thought.
Dmitri Mendeleev made the Periodic table.
Long dashes in the Mendellev's periodic table represent the element which were not discovered yet and these elements were discovered later on.
