Question

Begin by assigning one of each of the following elements to each group member: carbon, nitrogen, fluorine, neon, sodium, aluminum, phosphorus, chlorine, iron. Each person should complete the following five steps for their element: Write the electron configuration of the element. This can be copied from Question #1. Create an energy level diagram for your element. Use a line to represent an orbital, and use up and down arrows to represent spin of electrons in each orbital. Fill in the energy level diagram. Prepare a chart similar to the one shown in the example below, giving the values of each of the four quantum numbers for each electron in the atom. Fill in all of the quantum number assignments on the chart. As an example, we will complete the five steps for boron.
