Standard Chemistry - Electrons in Atoms test

- What were the three problems Bohr was trying to solve and how did he solve each of them?
- In the space below, draw Bohr’s model of the atom.
- What were the two problems with Bohr’s theory and how did Schrodinger solve them?
- How many types of orbitals are on level 4?
- How many different f orbitals are there?
- How many electrons can fit into each orbital?
- How many electrons can fit on level 4 (I want to see how you come up with this number!)
- In the space provided, draw the following orbitals.
- Write the electron configuration for the following elements and ions.

a) dx^{2}-y^{2} b) s

c) p_{z} d) d_{xy}

- Ru (#44)
- Ar (#18)
- Po (#84)
- Au (#79)
- F
^{-1}(#9) - Ba
^{+2}(#56) - Ru
^{+2}(#44 again) - Ru
^{+3}(still #44)

10. Which of the ions of Ru (from above) is the more stable and why?
