This was an old project i still dont understand it please help Instructions: Complete all three sections of this activity worksheet. To complete parts one and three, use the toolbar options of your word processing program to insert shapes such as arrows, curved lines, or circles. If you would rather complete the diagrams by hand, print this document and submit a scanned copy of the completed worksheet to your instructor.

Part One—Orbital Notation
Create orbital diagrams for the elements described below. Don't forget to consider Hund's rules when creating using orbital notation. An example has been done for you.
Example: An atom of the element aluminum has 13 electrons. Use orbital notation to diagram the probable location of its electrons.

1. An atom holds 7 electrons. Use orbital notation to model the probable location of its electrons.
2. An atom holds 22 electrons. Use orbital notation to model the probable location of its electrons.
3. An atom holds 17 electrons. Use orbital notation to model the probable location of its electrons.

Part Two—Quantum Numbers
Answer the questions on quantum numbers below. One example has been done for you. Example: What are the first two quantum numbers for the electrons located in subshell 2p? Energy level (n = 2), p subshell (l = 1)
4. What are the first two quantum numbers for the electrons located in subshell 4d?
5. What are the first three quantum numbers for the electrons located in subshell 2s?
6. How many electrons can be held in a sublevel l = 3?
7. How many electrons can be held in the energy level n = 4?
8. How many electrons in an atom can share the quantum numbers n = 4 and l = 3?

Part Three—Electrostatic Forces
Draw the pattern of electric field lines in the diagrams below to illustrate the forces between charged particles. An example has been done for you. Example: Draw the electric field lines between two positively charged particles.

9. Draw the electric field lines between two negatively charged particles. According to Coulomb's law, how would the electrical force between these particles change if they were moved farther apart?
10. Draw the electric field lines between a proton and an electron. According to Coulomb's law, how would the electrical force between these particles change if the product of their electrical charge increased?
