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 non-metals on the right.
A table of the elements, written in sequence in the order of atomic number or atomic weight and arranged in horizontal rows (periods) and vertical columns (groups) to illustrate the occurrence of similarities in the properties of the elements as a periodic function of the sequence.
At the completion of this episode's lesson(s), you should be able to: • Explain how the organization of the periodic table and its periodic tendencies relate to electron distribution. • Use the periodic table to write electron distributions. • Define period and family. • Determine the number of energy levels in an atom of an element.
The periodic table lists all the known elements by increasing atomic number, which is simply the number of protons in the nucleus. If that were the only consideration, the chart would be simply a line, but that is not the case.

The Periodic Table of Elements is organized by the elements' atomic mass. It is also organized into groups and periods. The periods are the horizontal rows. They change from left to right in a predictable pattern. The vertical rows are called groups, or families.
The periodic table is organized like a big grid. Each element is placed in a specific location because of its atomic structure. As with any grid, the periodic table has rows (left to right) and columns (up and down). Each row and column has specific characteristics.
The periodic table is one of the most valuable tools for chemists and other scientists because it orders the chemical elements in a useful way. Once you understand how the modern periodic table is organized, you'll be able to do much more than look up element facts, like their atomic numbers and symbols.
Periodic table of the elements: 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.
