Today there are 111 elements recognised by IUPAC, and these are usually displayed in the form of a matrix called a periodic table. The term periodic came from the regular occurrence of certain chemical properties in the list of known elements when these are arranged in order of increasing relative mass.

The periodic table has a special name for its columns, too. When a column goes from top to bottom, it's called a group. The elements in a group have the same number of electrons in their outer orbital. Every element in the first column (group one) has one electron in its outer shell.

Instead, you will see them in a brightly colored grid or table (something like a calendar) that has nothing to do with alphabetical order at all. This familiar table is called "The Periodic Table of the Elements".

because there are periodic traits on the table i guess... for example all the noble gases have same traits and those elements appear periodically.

Compiled a Periodic Table of 56 elements based on the periodicity of properties such as molar volume when arranged in order of atomic weight. ... These new elements were part of a new block of the Periodic table called Actinides. Seaborg was awarded a Nobel Prize in 1951.
