the periodic table changes by the mass number over the time it changed now by atomic number
How have chemists used the Periodic Table over time
no because if you look back in time more they didn't know as much as we do now so we learn more over time so if you looked back in time you wold see that there would be gaps in random spots on the periodic table. :)
Changes that repeat themselves after a fixed interval of time are periodic changes. eg. day and night formation. Changes that do not repeat themselves after a fixed interval of time are non periodic changes.eg. tornado i.e. a natural calamity.
The periodic table was considered complete in 1869 when Dmitri Mendeleev published his version of the periodic table which arranged elements by atomic weight and properties. However, the table has been updated and refined over time to include new elements and conform to our modern understanding of atomic structure.
dmitri Mendeleyev was in a university in St.Petersburg Russia when he made the periodic table...hope this answers your question...jo_phil

multiple people over time
New elements have been discovered or synthesized and added to the Periodic Table.

August 20, 1864 was when John Alexander Reina Newlands produced the first periodic table of the elements.
Periodic changes are those changes that repeat themselves at frequent intervals of time. Non periodic changes are those changes that do not repeat themselves at regular intervals of time
periodic is a game

The periodic table of elements was created by Dmitri Mendeleev, a Russian chemist, in 1869. He arranged the elements based on their atomic mass and properties, and left gaps for elements that were yet to be discovered. Over time, new elements were discovered and added to the periodic table by various scientists.

A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
