Question

6. (a) The quantum number n describes the of an atomic orbital and the quantum number l describes its .

(b) When n = 3, the possible values of l are:

(c) What type of orbital corresponds to l = 2?

(d) What type of atomic orbital has 2 nodal planes?

(e) The maximum number of orbitals that may be associated with the quantum number set n = 3, l = 2, and ml = -2 is

(f) How many subshells are in the n = 4 shell?

(g) How many orbitals are in the n = 3 shell?

(h) How many orbitals are in the l = 0 subshell?

(i) The maximum number of orbitals that may be associated with the quantum numbers n = 5 and l = 1 is

Answer 1

6. a) . The quantum number n describes the of an energy atomic orbital and the quantum number l describes its shape of orbital

b. l values are 0 to n-1

n = 3    l = 0,1,2

c. l = 2

dxy, dyz, dzx, dx^2-y^2 , dz^2

d.   Each d-orbital has 2 nodal planes

e. n = 3, l = 2, and ml = -2 is 1 orbital

Each m value indicate the one orbital

f. n = 4 l = 0,1,2,3

Each l value indicate the subshell.

n = 3 contains 3 subshells . They are 4s,4p,4d, 4f

g. no of orbitals = n^2

                           = (3)^2 = 9 orbitals

h. l = 0 subshell contains one orbitals

i. n = 5 and l = 1 ----------> 5s   ------------>one orbital

h. l = 0
