2) Show the three ways of writing the symbolic representation of an isotope (use Carbon-13).
3) How many protons, electrons and neutrons are in a Carbon-13 isotope?
4) Define atomic mass.
5) If an atom has 2 isotopes and one (call it X-21) has a percent abundance of 95.5% and other (call it X-23) has a percent abundance of 4.5%. Would the atomic mass be CLOSER TO X-21 actual mass, or CLOSER TO X-23 actual mass or ABOUT IN MIDDLE OF BOTH? Explain your answer.
6) Using the blank Atomic mass calculation table ([Blank Atomic Mass Calculation Table]) and the isotope information below, show the work for calculating the atomic mass for this element.
Chlorines 2 isotopes:
Cl-35 Percent abundance (75.78%) and actual mass of one isotope (34.968 amu / isotope)
Cl-37 Percent abundance (24.22%) and actual mass of one isotope (36.965 amu / isotope)
