Mendeleev invented the periodic table in 1869.
In those days there were still elements missing, they had no idea of what electrons were or how they related to chemistry, or how the nucleus related to atomic weight.;
but they're really the same charts.
There are more elements and it's organized differently
Dmitri Mendeleev is credited with developing the modern periodic table in 1869. He arranged the elements based on their atomic mass and chemical properties, predicting the properties of undiscovered elements. Mendeleev's table laid the foundation for the periodic table we use today.
The modern periodic law was proposed by the Russian chemist Dmitri Mendeleev in 1869. He arranged the elements in order of increasing atomic mass and grouped them based on similar chemical properties, leading to the development of the periodic table.
Dmitri Mendeleev is considered the father of the periodic table. He created the first widely accepted version of the periodic table in 1869, arranging elements based on their properties and atomic weights. Mendeleev's table laid the groundwork for the modern periodic table.
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.

Not all the elements were included
Dmitri Mendeleev was the first to develop the modern periodic table in 1869. Later, Henry Moseley rearranged the elements by atomic number, which is the modern arrangement. So, Mendeleev comes before Moseley in terms of their contributions to the modern periodic table.
