Periodic table of chemical elements.

is based on atomic weight.

A list of chemical elements sorted from smallest to largest. The list is roughly rectangular in shape, with spaces in the period of some elements, so that elements with similar characteristics are grouped into the same group, such as alkali metal elements, alkaline earth metals, halogen elements, and noble gases.

Non-metallic, transition elements, etc.

This makes the Zhou Chiye period form an elemental partition and is divided into seven main clans, seven secondary clans, clans, and 0 clans. Because of its ability to accurately ** the properties of various elements and the relationships between them, it is widely used in chemistry and other scientific fields as analytical chemistry.

Useful frameworks for behavior.
