1) Define Isotope:<br> <br> 2) Show the three ways of writing the symbolic representation of an isotope (use Carbon-13).<br> <br> <br> 3) How many protons, electrons and neutrons are in a Carbon-13 isotope?<br> <br> <br> 4) Define atomic mass.<br> <br> <br> <br> 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.<br> <br> <br> 6) Using the blank Atomic mass calculation table ([http://www.tmcleod.org/Level1/Chem328BlankAtomicMassCalculationSheets.pdf Blank Atomic Mass Calculation Table]) and the isotope information below, show the work for calculating the atomic mass for this element.<br> *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) <br> <br> <br>
