Why is the mass number of an isotope always a whole number?
Different isotopes of the same element have different mass numbers because their nuclei contain different numbers of neutrons. The symbol is read “uranium-238.” The mass number is always a whole number; it is a count of the particles.Click to see full answer. Regarding this, why is the mass number of an isotope a whole number?Yes,…

The symbol is read “uranium-238.” The mass number is always a whole number; it is a count of the particles.Click to see full answer. Regarding this, why is the mass number of an isotope a whole number?Yes, it is a whole number because it is the sum of the number of protons, neutrons, and electrons in an atom. No, the mass number is the mass compared to the mass of carbon−12. Yes, it is a whole number because it is the sum of the number of protons and neutrons in an atom.Likewise, is the mass of an isotope a whole number quizlet? The sum of the protons and neutrons in the nucleus for ONE atom and is always a whole number. Average of the mass of different isotopes according to their abundance and is usually a decimal. Listed on the periodic table. An isotope has 35 electrons and 47 neutrons write the isotope notation. Furthermore, why is the actual weight of an isotope not a whole number like the mass number? Atomic mass is never an integer number for several reasons: The atomic mass reported on a periodic table is the weighted average of all the naturally occuring isotopes. The mass of an atom isn’t what you’d get by adding up the masses of its individual protons, neutrons and electrons.Why the mass number of chlorine is not a whole number?The reason that the masses aren’t integers (whole numbers) is that there are different isotopes of the same element. This means that they have the same number of protons and electrons but a different number of neutrons. Chlorine is roughly 75% Cl and 25% Cl . Chlorine is roughly 75% Cl and 25% Cl .
