Mô tả sản phẩm
The periodic table of elements in English is simply called the **Periodic Table** or sometimes the **Periodic Table of the Elements**. It's a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and recurring chemical properties.
Understanding the Periodic Table
Arrangement and Organization
The elements are arranged in order of increasing atomic number (number of protons in the atom's nucleus). Rows are called periods and columns are called groups or families. Elements within the same group share similar chemical properties due to having the same number of valence electrons (electrons in the outermost shell).Key Information Provided
Each element's box on the periodic table typically includes its symbol (e.g., H for hydrogen, O for oxygen), atomic number, and atomic mass. Some tables also include other information such as electron configuration and electronegativity.Importance and Use
The periodic table is an essential tool in chemistry and related fields. It allows scientists to:- Predict the properties of elements.
- Understand the relationships between different elements.
- Design and synthesize new materials.
- Explain chemical reactions.
