Introduction
The periodic table is a fundamental tool in chemistry that helps us understand the properties and behavior of elements. It is a tabular arrangement of elements, organized by their atomic number, electron configuration, and recurring chemical properties. However, the periodic table is not complete without the missing components, which are indicated with orange letters. In this article, we will complete the table by filling in the corresponding numbers or symbols below.
The Periodic Table
The periodic table is a two-dimensional table that consists of rows called periods and columns called groups or families. The elements are arranged in order of increasing atomic number, which is the number of protons present in the nucleus of an atom. The periodic table is divided into several blocks, which are based on the electron configuration of the elements.
| Group | 1 | 2 | 13 | 14 | 15 | 16 | 17 | 18 |
|---|---|---|---|---|---|---|---|---|
| A | H | He | ||||||
| B | Li | Be | ||||||
| C | Na | Mg | ||||||
| D | K | Ca | ||||||
| E | Rb | Sr | ||||||
| F | Cs | Ba | ||||||
| G | Fr | Ra |
