Write your answers on your blank page and be prepared to upload a photo to this Quiz Assignment. 1. a. Write the Electron Configuration for Phosphorus b. Draw the Orbital Diagram for Phosphorus c. In your own words, and referencing to the Electron Configuration & Orbital Diagram for Phosphorus describe how you used the Aufbau Principle, Hund's Rule and the Pauli Exclusion Principle. Include enough detail that would help to explain these concepts to someone for the first time.

18- Which statement regarding the Bohr model of the atom is correct? A. Energy levels are electrons orbiting the nucleus are continuous B. As electrons get further away from the nucleus their energy levels decrease C. Energy levels of electrons orbiting the nucleus is quantized D. Electron energies around the nucleus are positive in value

Draw an “energy level diagram” for a calcium (Ca) atom. HINT: Use the periodic table to determine the number of electrons that are present in a krypton atom. An empty (no electrons) energy level diagram for multi-electron atoms is shown on the left. Electrons are arranged (configured) into the orbitals in the way that results in the lowest possible energy. Nature does this by obeying the Aufbau Principle, the Pauli Exclusion Principle, and Hund’s Rules. See the hint from the previous question (3.2) for more details. EXPLANATION: A calcium atom has 20 protons and therefore 20 electrons. Electrons are arranged (configured) into the orbitals in the way that results in the lowest possible energy. Nature does this by obeying the Aufbau Principle, the Pauli Exclusion Principle, and Hund’s Rules. See the hint from the previous question (3.2) for more details. Note that the 4s orbital fills before the 3d orbital because the 4s orbital lower in energy than the 3d orbitals (the 3d orbitals are…
