Question

What number of atomic sequence numbers indicate?

(plz no clown answers from internet, answer in simple sentences)​

Answer 1

Answer:

As of 2019, 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.
