Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.

DiscoVery of new elements
He left too many spaces between the elements......

Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
it has elements
To understand the concept of Periodic Table
DiscoVery of new elements
He left too many spaces between the elements......
because they did not feel that his table was well enough to be used world wide.
Mendeleev's periodic table of elements certainly wasn't created in 1901
they changed the 3 new Elements.
elements
Comparing the properties of the new element with the properties of the other elements in the group we can make this prediction.
not if u mean completely filled in but square by square yes
Mendeleev's table was more systematic. Elements were arranged in order of atomic masses.
