Mar The element europium has two naturally occurring isotopes: 151 Eu and 153Eu. The 151 Eu isotope has a mass of 150.9196 amu and that of 153Eu is 152.9209 amu. Which one statement about europium is FALSE? O a The nucleus of every 163Eu atom in the universe contains 90 neutrons. Ob The natural abundance of 153 Eu is 52.2%. OcEuropium is not a non-metal. Od. The natural abundance of 151 Eu is 52.2%. Oe. The reason for the mass of each isotope being lower than its mass number is the mass used to create the binding energy that keeps all the protons and neutrons in the nucleus.
