HW #2 (Chapter 2: Atoms, Molecules and Ions)
Name Useni Kaite
1. What is the difference between an atom and an ion? What would the atomic symbol be for
something with 15 p*, 15 nº, and 18 e (including charge, atomic and mass number)?
2. Pick one of the founding experiments' of the atomic structure. In your own words, briefly
explain the setup and highlight the main conclusions.
3. Using your book or an online source, pick an element.
a. Report the diameter of that type of atom in angstroms.
b. What would the radius (d/2) of the atom be in meters?
C.
How many atoms would you need to line up to span 24μm?
d. Calculate the volume of a sphere the size of your atom. V=(4/3)лr³
4. Define atomic number and mass number. How do these two things relate for two isotopes?
5. Assume your professor discovered a new atom, Borkium. If there were only two major isotopes
Brk-300. amu which represents 78.2% abundance and Brk-310. amu which represents 21.8%,
what would the molar mass of Borkium be reported as?
6. How many of each type of atom are in the following:
a. Cu(C₂H5CO2)2
b. (NH3)4PO4
