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.

  • 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.

    What is a color-coded periodic table?

    A:

    In a color-coded periodic table of the elements, the box for each element is colored. This color represents the classes of elements, which include metals, metalloids and non-metals. In general, the color blue is used for metals, orange for metalloids and green for non-metals. The periodic table may be further color-coded to include other groups such as transition metals, rare earths, alkali metals, alkaline earths, halogens and noble gases.

    How is the modern periodic table arranged?

    A:

    The modern periodic table is arranged in ascending order according to atomic number. An element's atomic number is equal to the number of protons in each atom. Within this order, elements are arranged into distinct groups that share properties.
