Question
Please write clearly and answer 1 to 9 in simple form Quantum Number Problems Use the rules for quantum numbers and nodes to answer the questions below: E=-K for k-2.179x10-18 J (1) n= 1,2, (2) (3) Rules so 1=0, 1, 2, 3 n-1 ors(I=0), p (1-1), d (1-2), f(1-3),g(1-4) m, =-l,-/+1,..0, +1 (e.g., when 1-1, m.,--1,0, +1) (4) The number of nodal planes, No , is equal to the angular momentum quantum number, . This means 1-Np (5) The total number of nodes is Nr No+Ns, where N, is the number of spherical nodes. Ny-n-1 where n is the principle quantum number. So n Np + N, + 1 From theses orbitals: 2s 3p 4d 5f 6s fill in the following blanks with at least one correct answer. I. The orbital with 1= 2 2. The orbital with n 3 3. The orbital that can have m/- -3 4. The orbital with the highest energy- - 5. The orbital with 1 planar node 6. The orbital with 5 spherical nodes 7. The orbital with a total of 3 nodes 8. The subshell with exactly three orbitals 9, The orbital with 8 lobes ofprobability densityExplanation / Answer
Q1
orbital l = 2
if l = 2, then orbital must be "d"; choose 4d
Q2
if n = 3, then 3X; from the list, only 3p
Q3
if orbital ml = -3, then l = 3, meaning that n = 4 at least, so 4d, 5f only
Q4
highest energy --> 5f > 6s
then 5f
Q5
1 planar node --> 3p at least
Q6
orbital with 5 spherical nodes
spherical nodes --> n-1; then for 5, this n = 5+1 = 6
chooose 6s
