Sf f. 5g 7) Give then and I quantum numbers for the following subshells: a. 4p b. 5d I c. 3s d. 4f 8) What is the subshell designation (e.g. 2p, 3d...) for the following cases? a) n=2, l = 0 b) n= 4, l = 3

Answer 1

3) Answer is 1s,2s,2p,3s,3p,4s,3d. Using Aufbau principle we get this order.

4) a) 3 orbitals. As p subshell contain 3 orbitals.

b) 1 orbital. As s subshell contain 1 orbital only.

c) 1 orbital.

d) 5 orbitals because d subshell have 5 orbitals.

e) 7 orbitals.

f) 25 orbitals. Number of orbitals = n ^2.
