The quest for new elements is usually described using atomic numbers. As of 2024, all elements with atomic numbers 1 to 118 have been observed. Synthesis of new elements is accomplished by bombarding target atoms of heavy elements with ions, such that the sum of the atomic numbers of the target and ion elements equals the atomic number of the element being created.

That means r varies as A 1 / 3, so ( Z 2 / r 3) = K = ( Z 2) / A. K is called a "fissility parameter." A given value of K defines a set of nuclei which have similar liquid-drop-model barriers against spontaneous fission.

WebThis is a list of the 118 chemical elements that have been identified as of 2024. A chemical element, often simply called an element, is a type of atom which has the same number of protons in its atomic nucleus (i.e., the same atomic number, or Z ). [1] WebThis list contains the 118 elements of chemistry. For chemistry students and teachers: The tabular chart on the right is arranged by melting point. The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon. The unity used for the melting point is Celsius (C).
