there are 118 known chemical elements. These elements are arranged in the periodic table based on their atomic numbers and properties. However, it is possible for new elements to be created through a process known as nuclear transmutation.
Nuclear transmutation involves changing the number of protons in an atomic nucleus, which effectively changes the element. Scientists have successfully created new elements in laboratories by bombarding target atoms with accelerated particles. For example, elements beyond atomic number 92 (uranium) have been synthesized in this manner.
The discovery and creation of new elements often require highly specialized and advanced experimental techniques. The newly created elements are typically highly unstable and decay rapidly into other elements. They are usually classified as synthetic elements, and their existence is primarily of scientific interest.
It's worth noting that since I'm not interested in that topic as much as i used to and my answer might be a bit outdated is in 2021, there may have been further discoveries or advancements in the field of element synthesis beyond that time. It's always good to consult updated scientific sources for the latest information on this topic.
