In 19th century , Mendeleev organised periodic table. He organised it in year 1869.
Dmitri Mendeleev created the periodic table in 1869, which organized the known elements based on their atomic properties and characteristics. Mendeleev's periodic table played a significant role in predicting the properties of undiscovered elements and has been the foundation of the modern periodic table.
Dmitri Mendeleev focused on his research mainly during the mid-to-late 19th century, with his most notable work on the Periodic Table occurring around 1869. He continued to refine and expand his research until his death in 1907.
No, he did not know about it. Helium was discovered in spectrographs of the Sun in 1868 and isolated in 1895. Mendeleev's original table skipped from hydrogen (1) to lithium (3).
if you are going to be a scientist or are going to study physical science, then it would be beneficial for you to learn about the periodic table. it will especially be beneficial for you to memorize it if you're going to high school, because you need to memorize it for your freshmen year.

The first slightly inaccurate Periodic Table of Elements was invented in the mid 1800's. Then Henry Mosley found the mistakes and re-corrected them in the early 1900's, which now is our current periodic table that we use.
