Periodic table - Elements, Properties, Periodicity: The periodicity of properties of the elements is caused by the periodicity in electronic structure. The noble gases are chemically unreactive, or nearly so, because their electronic structures are stabl
Periodic table - Elements, Groups, Properties: The noble gases—helium, neon, argon, krypton, xenon, radon, and oganesson—have the striking chemical property of forming few chemical compounds. This property would depend upon their possessing especially

This periodic table of elements provides comprehensive data on the chemical elements including scores of properties, element names in many languages and most known nuclides (Isotopes). Below the table there is a "Periodic Table Sorted By" section with links that will sort chemical elements by vario...
Modern Periodic Table According to Moseley, all the physical and chemical properties of an element are the periodic function of its atomic numbers. In the modern periodic table, there is a total of seven periods and eighteen groups. In the periodic table elements, two horizontal rows contain fou...
In the periodic table of the elements, elements are arranged in a series of rows (or periods) so that those with similar properties appear in vertical columns. Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more ...
78.1. THE PERIODIC TABLE 元素周期表 (图片可点击放大) In this section, we will explore the periodic table, which organizes chemical elements and provides valuable information about their properties and relationships. Understanding the periodic...
