Their electron configurations are 1 s 1 and 1 s 2, respectively; with He, the n = 1 shell is filled. These two elements make up the first row of the periodic table (Figure 9.7. 2)
WebA modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with similar properties in the same vertical column ( Figure 2.26 ). Each box represents an element and contains its atomic number, symbol, average atomic mass, and (sometimes) name. WebThe periodic table is organized like a grid. In this article, we will explain how the grid organizes the elements. Understanding how the elements are organized in the grid may help you to learn the periodic table. The position of each of the elements is not at all random but due to its atomic structure. Grid Structure
