Elements 4.6: The Periodic Table of the Elements - Chemistry LibreTexts List of chemical elements - Wikipedia Periodic table - Wikipedia The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order of their atomic numbers an approximate recurrence of ... The periodic table of the elements contains all of the chemical elements that have been discovered or made; they are arranged, in the order of their atomic numbers, in seven horizontal periods, with the lanthanoids (lanthanum, 57, to lutetium, 71) and the actinoids (actinium, 89, to lawrencium, 103) indicated separately below. Learn about the origin, distribution, and properties of the 118 known chemical elements, the fundamental substances of which all matter is composed. Explore the historical development of the concept of element from ancient Greek philosophy to modern chemistry. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ).
