Questions and Answers

What is the fractional atomic mass of neon?

  • 22.82 amu
  • 21.26 amu
  • 20.18 amu (correct)
  • 20.92 amu

    • Which isotope of neon has the highest percentage in the sample?

  • 21 10Ne
  • Isotopic percentages are not related to the mass of the isotopes
  • 20 10Ne (correct)
  • 22 10Ne

    • Why is the average atomic mass of neon considered to be 20.18 amu?

  • It is an arbitrary value chosen for convenience in laboratory purposes (correct)
  • Because all neon atoms in the sample have a mass of exactly 20.18 amu
  • It is the sum of the individual atomic masses of the isotopes
  • It is the mass of the most abundant isotope in the sample

    • What does the percentage given for each isotope represent?
