The isotope of an atom contains 40 protons and 51 neutrons suddenly has two neutrons added to it. What isotope is created? 1.Antimony-39 2.Zirconium-93 3.Antimony-53 4.Zirconium-53
I believe the correct answer from the choices listed above is option 2. The isotope of an atom that contains 40 protons and 51 neutrons and suddenly has two neutrons added to it would be Zirconium-93. We look at a periodic table and find the element with the atomic number 40 which equal the number of protons.
