Who made the first periodic table?
Mendeleev discovered the periodic table (or Periodic System, as he called it) while attempting to organise the elements in February of 1869.
Was Mendeleev the first person to make a periodic table?
Dmitri Ivanovich Mendeleev, however, was the first person that made a periodic table that was very close to the one we today. Mendeleev’s table consisted of the 60 elements that were known at the time. He was a Russian chemist, and he was focused on arranging the elements according to their atomic mass.
Who is known as the father of the periodic table?
Dmitri Mendeleev, Russian in full Dmitry Ivanovich Mendeleyev, (born January 27 (February 8, New Style), 1834, Tobolsk, Siberia, Russian Empire—died January 20 (February 2), 1907, St. Petersburg, Russia), Russian chemist who developed the periodic classification of the elements.

Who created the second periodic table?
In 1869 Russian chemist Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass. He predicted the discovery of other elements, and left spaces open in his periodic table for them.
What is the oldest element?
Measuring how many of the new elements are present tells scientists how long the grain was exposed to cosmic rays. This in turn informs them how old it is. Some of the pre-solar grains turned out to be the oldest ever discovered.
Who is modern periodic table?
Mendeleev’s Periodic Table. Mendeleev, who first published his periodic table in 1869 (Figure 3.2. 1), is usually credited with the origin of the modern periodic table.
What is the history of periodic table?
In 1869 Russian chemist Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass. He predicted the discovery of other elements, and left spaces open in his periodic table for them. In 1886 French physicist Antoine Bequerel first discovered radioactivity.
When was the first element discovered?
The ‘first’ chemical element Phosphorous (P) was the first chemical element to be discovered after the ancient times by German alchemist Hennig Brand in 1669. At the time, Brand was trying to create the philosopher’s stone, a legendary alchemical substance that was thought to turn metal into gold.
When was the first periodic table made?
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered.
Has element 119 been discovered?
