How many neutrons does barium have?

Each isotope of an element has a different number of neutrons.Number of neutrons = Atomic mass of the isotope - Atomic number of the elementThe atomic number of barium is 56.For a list of barium isotopes see the link below.The answer it wants is 81.


Which element has atomic number of 56 and mass number of 137?

The element with atomic number 56 is Barium (Ba). Given the mass number of 137, it means there are 137 total particles in the nucleus (protons and neutrons combined), so the number of neutrons for this isotope of Barium would be 137 - 56 = 81 neutrons.

How is an element with 56 protons and 82 neutrons related to an element with 56 protons and 78 neutrons?

They are both Isotopes of Barium. The 56 protons tell us that the element is Barium and when you add the neutrons with the protons you get barium138 and barium134. They are both stable isotobes of barium but of all the barium in the world about 72% is barium138 and 2% is barium134.
