The mass number of the isotope uranium-234 is 142.
the atomic mass number for uranium is 92
Uranium is a non metal element. Atomic mass of it is 238.
The atomic weight of uranium is 238,02891.
Uranium atomic number: 92 Uranium atomic weight: 238,02891 Uranium number of protons: 92
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
Atomic mass number = Number of protons + Number of neutrons Number of protons of uranium nucleus is 92. The number of neutrons is different for each isotope. Example for 238U: 92 protons + 146 neutrons = 238
