The elements with atomic numbers greater than 92 are all human-made. What element was produced when Es-253 was bombarded with an alpha particle, producing a new element and a neutron? Include the atomic number, symbol, and mass number.

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.
