The long form of Periodic Table has the advantage to present all chemical elements in order of the atomic number; but this form is not usual because is not adequate for printing.
The element radium (symbol Ra) is in period 7.
Mendeleev couldn't predict the existence of noble gases because they are inert and do not readily form compounds with other elements. Mendeleev's periodic table was based on the properties of elements and their compounds, and since noble gases do not readily form compounds, they did not fit into his classification scheme.
In 1869, he published the greatest of his works, Principles of Chemistry, where he formulated his famous periodic table, translated into many languages ​​and that was a textbook for many years.
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
there are many different styles of the periodic table.they use different topics. like the mendeleev periodic table is focused on protons. and the kimyaokulu is focused on the s,p,d,and f shields
atomic number Chemical elements are organized in the form of the periodic table of Mendeleev, in groups and periods.
Mendeleev arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Dmitri Mendeleev is credited with the creation of the modern periodic table in 1869. He arranged the elements based on their atomic mass and properties, predicting the existence of yet-to-be-discovered elements and leaving gaps for them in the table.
The element radium (symbol Ra) is in period 7.
Dmitri Mendeleev is credited with developing the periodic table in a form close to its modern version. He arranged the elements based on their properties and left gaps for undiscovered elements, predicting their properties accurately. This work was inspired by his experience organizing playing cards into sets.

He discovered the elements and and weighed them and latter placed the elements in order to form the periodic table.

There have been two make ups of the periodic table so far Mosley made the first one but was overtaken by Dimitri Mendeleev's form, which we use today.
He invented the periodic table. You must know what that means; he was the father of basic chemistry. Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
