-
The periodic table of elements can be described as table which shows the arrangement of chemical elements ordered by atomic numbers in columns and rows. It turned out created by Russian chemist Dmitri Mendeleev in 1869 to determine the periodic trends in the properties of elements.


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

Collection
The next thunderstorm are listed according to their increasing atomic numbers. Rows are arranged in a manner that elements with the exact same properties fall under precisely the same 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 a few groups that enjoy non-systematic names as well. Not alone tend to be the groups on the periodic table, another groupings of elements often named as well. They're lanthanoids and actinoids.
