An atom has an atomic number of 56 yet has a mass number of 137 amu evalution of data indicates that the element is?
barium
What element has a mass number of 138 and atomic number of 56?
The atomic number is the number of protons; 56. The mass number is the number of protons plus the number of neutrons, so 56+82=138. The element is barium, by the way, because of the number of protons.
