10.12.2008 · A chemical element is a substance that cannot be further broken down by any chemical reaction. Each element has a unique number of protons in its atom. For example, a hydrogen atom has 1 proton, while a carbon atom has 6 protons. Varying the number of electrons in an atom of an element produces ions. Changing the number of neutrons produces ...

Feb 07, 2019 · The periodic table of elements is widely used in the field of Chemistry to look up chemical elements as they are arranged in a manner that displays periodic trends in the chemical properties of the elements. However, the Periodic table generally displays only the symbol of the element and not its entire name. Most of the symbols are similar to the name of the element but some symbols of elements have Latin roots.
