Yes, there are elements that have atomic numbers greater than that of uranium (Z = 92). These elements are known as transuranium elements, and they are all synthetic, meaning they are not found naturally on Earth. Here are some examples of transuranium elements along with their names and symbols:

  1. Neptunium (Np) - Atomic Number 93: Neptunium was the first transuranium element to be discovered. It was synthesized in 1940 by Edwin McMillan and Philip H. Abelson. It is named after the planet Neptune.

  2. Plutonium (Pu) - Atomic Number 94: Plutonium is perhaps the most well-known transuranium element due to its use in nuclear weapons and reactors. It was first synthesized in 1940 by Glenn T. Seaborg, Edwin McMillan, Joseph W. Kennedy, and Arthur Wahl. It is named after the dwarf planet Pluto.

  3. Americium (Am) - Atomic Number 95: Americium was discovered in 1944 by Glenn T. Seaborg, Ralph A. James, Leon O. Morgan, and Albert Ghiorso. It is named after the continent of North America.

  4. Curium (Cm) - Atomic Number 96: Curium was synthesized in 1944 by Glenn T. Seaborg, Ralph A. James, and Albert Ghiorso. It is named after Marie and Pierre Curie, the renowned physicists.

  5. Berkelium (Bk) - Atomic Number 97: Berkelium was first synthesized in 1949 by Glenn T. Seaborg, Stanley G. Thompson, Albert Ghiorso, and Kenneth Street Jr. It is named after the city of Berkeley, California, where the University of California is located.

  6. Californium (Cf) - Atomic Number 98: Californium was discovered in 1950 by Stanley G. Thompson, Kenneth Street Jr., Glenn T. Seaborg, and Albert Ghiorso. It is named after the state of California.

These are a few examples of transuranium elements with atomic numbers greater than uranium. There are additional transuranium elements with higher atomic numbers, but they are highly unstable and have short half-lives, making them challenging to study and characterize.
