This reason is, simply, very obvious. Compare the numbers: 238 and 16. Since the orbitals are more full, and the nucleus is packed tighter, and Uranium is located after atomic number 84, it is unstable. All of the elements after 84 are unstable. But that doesn't count isotopes of the earlier elements, because they can be unstable.

Does oxygen have a greater mass than chlorine?
Atomic oxygen does not have a greater atomic mass than chlorine, nor does molecular oxygen. The atomic mass of chlorine is approximately 35 g/mol, while molecular (O2) oxygen has a molecular mass of 32 g/mol.
Why does plutonium have a less mass then uranium?
Plutonium generally has a lower atomic mass compared to uranium because it has fewer protons and neutrons in its nucleus. Plutonium isotopes tend to have a smaller number of nucleons overall compared to most uranium isotopes, resulting in a lower atomic mass.
