1. Write balanced equations for the following nuclear equations by filling in
the missing particle or atom.
2. Classify each of the following elements as either a siderophile, lithophile, chalcophile or atomophile, and explain why you assigned each element the way you did. Explain where on earth (core, crust, atmosphere) you would expect to find the greatest amounts of this element.
a. Rh
b. Ag
c. Pt
d. V
e. Rb
f. Ar
3. Table 5.1 in lecture 1 gives the
chemical composition of the (1) universe, the (2) earth, and the (3) earth’s
crust. Based upon your knowledge of stellar evolution and synthesis of the elements,
explain how you would expect the chemical composition of the universe, the earth,
and the earth’s crust to be different if our solar system had formed 10
billion years ago rather than 5 billion years ago.
