The four elements (Arkan-e Arba’e) are one of the most fundamental concepts of nature in the Islamic period. The common idea about four elements is that with the discovery of Mendeleev's table, the theory of four elements was abandoned and it was thought that what they used to refer to as elements are not elements, but compounds. Examining the opinions of philosophers about the elements shows that water, air, fire and tangible earth that can be seen by examination are not elements, but compounds. Accordingly, the purpose of the current research is to investigate the elemental state of the four elements in correspondence with the elements of the periodic table. Therefore, this article deals with one of the basic questions about the elements, being what is the elemental state of the four elements, which is referred to as the elements, and why the tangible objects around us are not elements. The current research is descriptive-analytical in terms of type, fundamental in terms of purpose, and documentary in terms of method, and the information has been collected by referring to primary library sources. The results obtained from this research show that what is observed is not the pure state of the four elements and the element must be transparent; On this basis, not only earth, but also visible fire is not an element. Also, the meaning of the concept of "element" by the naturalists of the Islamic period is different from what is known as element today, hence there is a verbal similarity between the concept of element in the periodic table and the four elements and the meaning of these two, and they are not one.
