Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following describes the most probable location of an electron in an atom?
Nucleus
Electron shell
Orbital
Proton cloud
2. The principal quantum number (n) describes the electron's main energy level and its from the nucleus.
3. According to the Pauli Exclusion Principle, no two electrons in an atom can have the same set of four numbers.
4. Draw the Bohr model for a Fluorine atom (Atomic number 9). Label the nucleus and electron shells.
5. Hund's Rule states that every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied.
True
False
6. Write the full electron configuration and the noble gas shorthand configuration for Calcium (Ca). Explain the steps you took to determine these configurations.
