Abstract At the end of the 18th century, French chemist Lavoisier predicted that soil material such as lime were not simple substances. In the early 19th century, the British chemist Davy used electrochemical technology to prepare a new metal from lime and named it “Calcium”. The concept of calcium element was initially formed. Subsequently, with the advancement of the atom theory and the determination of the atomic weight of calcium, the concept of calcium had been developed. By the 20th century, the discovery of calcium isotope had given people a new understanding of the concept was calcium. In short, development history of calcium concept was not only the elements concept progressive process, but also the evolution history of scientific thought and scientific methods.
