. What are the allowed values of the quantum numbers through n = 4? 2. Write an orbital designation corresponding to the quantum numbers: a. n=4, l= 2, m, =0 b. n =3, = 1, m, =1 c. n =5, l= 1, m, =-1 d. n =4, I=3, m, = -3 3. What values l and m, are allowed for a principal quantum number (n) of 3? How many orbitals are allowed for n = 3? 4. Can an orbital have the quantum number n = 2, l = 2, m, = 2 5. For an orbital with n = 3 and m, = 1, what is (are) the possible value(s) €? 6. Which of the following orbitals do not exist: lp, 2s, 2d, 3p, 3d, and 3f​
