Q:

What are the vertical columns on the periodic table?

A:

Quick Answer

The vertical columns on the period table are called groups. There are 18 groups on the periodic table, and elements that are members of the same group share similar traits.

Full Answer

All elements in the same group have the same number of electrons in their outer electronic shell. Because of this, members of the same groups tend to receive and release the same number of electrons, which means elements in the same group share reactivity traits. For example, the noble gasses are a group, and none of these gasses react with any other elements because they all have full outer electronic shells.

    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:

    Why was the periodic table invented?

    A:

    The periodic table was invented by chemist Dmitri Mendeleev to organize and compare elements and understand their relations with each other. Mendeleev created the periodic table between 1868 and 1870 while writing his book titled "The Principles of Chemistry." Initially, Mendeleev created the chart for his personal benefit, but others quickly discovered its value, leading to its immediate acceptance and use by fellow chemists upon publication.
