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

c) What type of orbital corresponds to l = 3?

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 = 4, l = 3, and ml = -2 is

f) How many subshells are in the n = 5 shell? (g) How many orbitals are in the n = 3 shell?

h) How many orbitals are in the l = 2 subshell?

i) The maximum number of orbitals that may be associated with the quantum numbers n = 2 and l = 1 is

Answer 1

@ principal quantum numbey (n) represents majog energy shell to which an election belongs. It also describes the size and energy level of major energys shell Azimuthal quantum number (1) describes the shape and energy level of sub-shells in a major energys shell. when na3, the possible l' values are =o to nol = o to 3-1 . = o to 2 ie, 0,1,2 o lao (s-subshell) ② The plane at which zero electron densitys (=1 (b-subshell) exists is known as nodal plane (=2 (d-subshell) sonbital = zero nodal plane 1=3 (f-subshell) p-orbital = one nodal plane d-orbital = two nocal planes. @ n=4, L-3, m = -2 (=3 => for subshell & possible m' values are -3 -2 -1,0, 71, 72, 73 (seven degenerate froobitale) - Maximung number of oxbitals with n=4, L=3 & m =-2 is one ie, odbital is represented as 4f 6 n=5, No. of subshells=? Leo to n-1 - 0 to 5-1 = 0 to 4 -0,1,2,3,4 Ckve subshells) w n=3, No. of orbitals = n² = 3²= 9 orbitals. © L=2, No of opbitals = 21+1 = 2(3)+1 = 5 ofbitals ④ n=2, 6:1 21+1 = 20)+) = 3 orbitals (25) (Thice degenerate exbitals of ap = 2px, zby, 262)
