## Chemistry: Principles and Practice (3rd Edition)

a) 3 b) 3 c) 3 d) n=3, l=2, Possible values of $m_{l}$= -2, -1, 0, +1 or +2.
a) The number of subshells= the value of n= 3 b) For the p subshell, l=1. Total number of orbitals= 2l+1= $2\times1+1=3$ c) Maximum value of l= n-1= 4-1= 3 d) n=3, l= azimuthal quantum number corresponding to the d subshell= 2. Allowed values of $m_{l}$ ranges between the interval -l and +l. Therefore $m_{l}$= -2, -1, 0, +1 or +2.
