Did you know that the Periodic Table is organized by atomic number, which is the number of protons in an atom's nucleus? The Periodic Table currently contains 118 known elements, with the first being Hydrogen and the most recent being Oganesson. Elements are organized into groups and periods based on their chemical properties. Other interesting facts about the Periodic Table include the presence of lanthanides and actinides, two series of elements that are placed below the main table to maintain its compactness. The lanthanides are a group of 15 elements with atomic numbers ranging from 57 to 71, while the actinides are a group of 15 elements with atomic numbers ranging from 89 to 103. Additionally, each element on the Periodic Table has a unique symbol made up of one or two letters. For example, Oxygen is represented by O and Iron is represented by Fe. These symbols are derived from the elements' English or Latin names. Moreover, elements are classified into different categories such as metals, nonmetals, and metalloids based on their properties. Metals are typically good conductors of heat and electricity, while nonmetals are poor conductors. Metalloids have properties that are intermediate between metals and nonmetals. The Periodic Table is a cornerstone of chemistry and serves as a fundamental tool for scientists in understanding the behavior of different elements and compounds.
