Abstract Through the research and analysis of the development history of the concept of boron, it can be seen that the development of the concept of boron can be roughly divided into three periods:the formation of the hypothesis of boron, the formation and development of the concept of boron, and the establishment of the modern concept of boron. In the 18th century, Lavoisier predicted the existence of boron. In the early 19th century, the successful preparation of boron indicated the formal formation of the concept of boron. In the 20th century, with the establishment of atomic structure theory and the discovery of isotopes, people have a new understanding of boron. The development of the concept of boron is a process from putting forward the hypothesis to verifying the hypothesis, and constantly deepening the understanding. It is also a process of continuous progress of science and technology, gradual maturity of scientific theory and evolution and development of scientific thoughts.
