What is the mass number of europium?
Mass number is the number of protons and neutrons in the nucleus of an atom. And we might consider that the mass number of europium is 153 and call it good. Europium has an atomic number of 63, and there is only one stable isotope of it - europium-153. This isotope has the 63 protons and 90 neutrons. But there are other isotopes of europium, and their mass numbers range from 130 through 167 because europium has isotopes with neutron counts from 47 through 104.

Europium, with the chemical symbol Eu, is the chemical element with the atomic number 63.
Europium has a mass of 150.9196amu and a mass of m152.9209amu the average atomic mass of Eu is 151.96amu calculate the relative abundance of the two europium isotopes?
Let x represent the relative abundance of the isotope with mass 150.9196 amu and 1-x represent the relative abundance of the other isotope with mass 152.9209 amu. The average atomic mass formula is [(mass isotope 1)(abundance isotope 1) + (mass isotope 2)(abundance isotope 2)] = average atomic mass. Substituting the values given, you can set up a system of equations and solve for x to find the relative abundance of each isotope.
