Full Answer

There were 63 elements available in 1869 for Mendeleev to put on the periodic table. The current classification system came to fruition as scientists discovered more elements. Today, there are 109 elements on the periodic table. The table has a tabular arrangement and the basis of the arrangement of the elements includes the atomic number, recurring chemical properties and electron configurations.

  • Q:

    Who created the Periodic Table of the Elements?

    A:

    While the invention of the periodic table of elements is commonly attributed to Dmitri Mendeleev, the atomic weight sorting system was first conceptualized in 1862 by Alexandre-Emile Béguyer de Chancourtois. Despite releasing his table seven years before Mendeleev, Chancourtois' status as a geologist resulted in minimal exposure of his invention.

  • Q:

    How does Mendeleev's Periodic Table differ from the present one?

    A:

    Dmitri Mendeleev's periodic table featured elements arranged in accordance with their atomic mass, while the modern table has elements arranged according to periodic number. Mendeleev's periodic table also had the elements arranged vertically, whereas the modern table has them arranged horizontally.

  • Q:

    Why didn't Mendeleev arrange the elements by their atomic numbers when he created the periodic table?

    A:

    When Dmitri Mendeleev created the Periodic Table of the Elements, he decided against arranging them by their atomic numbers based on his correct assumption that those numbers were not totally accurate. When he first began to arrange the 60 known elements in the 1860s, he knew that new elements would eventually be discovered there are now over 100 known elements and that the atomic weights of the elements known at that time had been calculated incorrectly.

    When did beer flood the streets of London?

    A:

    Floods are no laughing matter, but they can be even more of a shock when they’re completely unexpected. The London Beer Flood occurred on October 17, 1814, when a brewery’s 22-foot-tall vat of beer exploded in London’s St. Giles neighborhood.
