Dmitri Mendeleev constructed the Periodic Table of elements in 1869 based on Atomic Mass( which is how much an atom weighs). this however was changed many many years later resulting in our current design of the periodic table which is based on atomic number instead.( the number of protons in an atom.)

Meyer contributions to the periodic table are?

Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to atomic number.

How are the elements arranged?

Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
