Who made the periodic table and what year?

A: Marie Curie and Pierre Curie/ 1898

B: Pierre Janssen and Joseph Norman Lockyer/1868

C: Dmitri Mendeleev/1869

The is answer: C

Dmitri Mendeleev/1869

In 1869 when Mendeleev was making the framework of the periodic table he would leave gaps for if their was to be new elements being discovered. He would arrange the elements with what there atomic weight was and if their atomic weight did match up or fit with the group he thought they would go with he would go and rearrange them until they went with the right groups and matched them up with similar properties. Dmitri Mendeleev was a russian chemist born on January 27th 1834 in a small Siberian Town and had received a master's degree 1856.
