Pattern
The weather are listed depending on their increasing atomic numbers. Rows are arranged in such a way that elements with similar properties succumb to the exact 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 numerous groups that enjoy non-systematic names as well. Not only will be the groups inside the periodic table, another sort of groupings of elements often named as well. They can be lanthanoids and actinoids.
