What is the mass number for the element uranium?
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
How do you find out the mass number?
Mass number = Number of protons + number of neutrons
