This number became known as an element’s atomic number. 后来,这个数字被称为元素的原子序数。 Today, elements on the periodic table are arranged by atomic number, which gives a more accurate understanding of element properties. 如今,元素周期表上的元素是按原子序数排列的,这使人们对元素的性质有了...
Periodic table of elements with information on chemical elements like gold, silver, iron, neon, helium, chlorine, copper, cobalt, and more
Periodic table, in chemistry, 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 t
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...
