10. Subshells in shell number two=2; designation=2s 11. Which subshell has greater energy, 3P or 3D? 3D, because it is increasing in size/energy. 12. a. What is the max number of electrons a 3D subshell can contain?- 10 b. What is the max number of electrons that can be held in the second shell? -8 c. What is the max number of electrons that can fit in a 3P orbital?- 2 d. What is the max number of electrons that can fit in a 4F subshell?- 14 e. What is the max number of sub shells that can be found in a shell number 4?-4 13. The valence shell is the one that is farthest away from the nucleus of the atom. 14. The number of the valence shell is the same as the period number (horizontal row) that the element is located. The number of the valence shell for the following is: A. MN- 4 b. Beryllium-2 c. Silicon-3 d. BR-4 15. The number of electrons in the valence shell is equal to the Roman numeral of any “A” group (vertical) in which the element is located. Ex. Element is group a 3A would have 3 valence electrons Electrons in the of the valence shell of the following elements: 1. P-5 2. Calcium-2

3. CL-7 4. Arsenic-5 Valence shell and number of electrons for the following: 1. Sulfur- 3, 6 2. NE- 2, 8 3. Potassium- 4, 1 4. Aluminum- 3, 3 Chapter 4 1. In the electron dot formulas, the dots around an elements symbol represent valence electrons. 2. Electron dot formula for the following elements: Attached in photo 3. Lewis Structures: Attached in photo 4. According to the octet rule, all atoms will lose of gain electrons in order to achieve a valence shell with eight electrons.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
