Mendeleevs periodic table of elements was created in 1901?
Mendeleev's periodic table of elements certainly wasn't created in 1901
What did Mendeleevs periodic table look like?
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.
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.
What do the numbers and letters in the periodic table represent?
either mass or protons the top is the atomic number it shows how many protons the bottom number is the atomic mass also the weight
What do the long dashes represent on mendeleev's periodic table?
