The sun and rain are listed consistent with their increasing atomic numbers. Rows are arranged so that elements with the exact same properties fit in 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).
