Elegant Au Periodic Table
The periodic table of elements is actually a table which shows the arrangement of chemical elements ordered by atomic numbers in columns and rows. It was eventually introduced by Russian chemist Dmitri Mendeleev in 1869 to look for the periodic trends within the properties of elements.

This periodic table includes the names symbols and atomic numbers of the elements

The elements are listed depending on their increasing atomic numbers. Rows are arranged to the extent that elements with the exact same properties set identical vertical columns. The groups or columns are numbered 1-18. The arrangement is Group 1(alkali metals), Group 2(alkaline earth metals), Group 15 (pnicogens), Group 16(chalcogens), Group 17(halogens) and Group 18(noble gases). There are many groups that enjoy non-systematic names as well. Not simply might possibly be the groups around the periodic table, a few other groupings of elements often named as well. They are lanthanoids and actinoids.
