- Synthetic elements, also known as artificial elements or man-made elements, consist of a series of 24 chemical elements on the periodic table1. These elements span from atomic number 95 to 118, specifically from americium (Am) to oganesson (Og)1. Promethium (atomic number 61), Astatine (atomic number 85), Francium (atomic number 87) and the transuranium elements constitute the synthetic elements2. Element 113, nihonium, was created by a Japanese team; the last five known elements, flerovium, moscovium, livermorium, tennessine, and oganesson, were created by Russian–American collaborations and complete the seventh row of the periodic table3.Learn more:✕This summary was generated using AI based on multiple online sources.
