The weather are listed according to their increasing atomic numbers. Rows are arranged in a way that elements with the exact same properties set the 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). Usually there are some groups that enjoy non-systematic names as well. But not only could be the groups on the periodic table, another sort of groupings of elements often named as well. There're lanthanoids and actinoids.
