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:

    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.

  • Q:

    Why is the periodic table useful?

    A:

    The periodic table is useful because it identifies and arranges all known elements in an informative manner. Elements are arranged into periods and families. The elements in each family or period may have similar or dissimilar physical and chemical properties.

  • Q:

    How is the periodic table organized?

    A:

    The elements in the periodic table are organized by their atomic numbers, their electron configurations and the recurring properties found in them. Elements are arranged in blocks, with elements found in that block all containing consistent properties. For instance, all alkali metals are highly reactive, and all noble gases are inert, meaning they cannot react with other elements under normal conditions.

  • Q:

    Which metals on the periodic table are magnetic?

    A:

    Three elements on the periodic table are magnetic: iron, nickel and cobalt. There are also a number of metals that take on slight magnetic properties when subjected to a magnetic field.
