Mendeleev arranged the elements by their relative Atomic Mass. Each one of his rows began with an element that had 1 valency and ended it with inert gas elements.

The creator of the Periodic Table, Dimitri Mendeleev, arranged the elements by atomic number (amount of electrons) and amount of electron shells. This then lead to columns (groups) of elements with the same amount of electrons in their outer shell.

So, now, every period contains elements with ascending atomic numbers. Every group contains elements with ascending amounts of electron shells.

What is mendeleev's periodic law?

The physical and chemical properties of the elements are periodic functions of their atomic numbers.The periodic law states that the physical and chemical properties of elements are periodic functions of their atomic numbers. They influence the characters of an element more than atomic weight.


How did this Russian scientist first arrange the elements?

Dmitri Mendeleev arranged the elements in his periodic table based on their atomic masses and chemical properties. He left gaps for undiscovered elements and predicted their properties accurately.


What was Mendeleevs proposal?

Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.


Mendeleev arrange the known chemical elements in a table according toincreasing?

Mendeleev arranged the known chemical elements in a table according to increasing atomic mass and similar chemical properties. This arrangement led to the periodic table of elements, where elements with similar properties fall into the same column or group. This organization allowed Mendeleev to predict the properties of undiscovered elements and leave spaces for them in the table.
