The Periodic Table - Groups, Periods & Atomic Number ...

The Periodic Table is probably one of the most iconic scientific documents, a single table that holds within itself almost all chemical knowledge amassed by man. The periodic table is a tabular arrangement of 118 elements, organized by atomic number, number of free electrons, and grouped together by similarity in chemical properties.

Jul 25, 2019· Periodic table of the elements, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the 'periodic law' in their properties, in which elements in the same column (group) have similar properties.

The Difference Between an Element Group and Period

Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.
