The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. #2-118
The period table is a display of the chemical elements , which are arranged by atomic number, electron configuration and recurring chemical property. There are 118 elements on the periodic table
When you put 355/113 in the calculator you get 3.14159292 and when you put 22/7 in the calculator you get 3.142857143..... But pi =3.141592654... which means 355/113 is the closest to pi.
