Question

1. How many orbitals in an atom can have the designation 5p, 3022. 4d, n=5, n = 4 2. Give the maximum number of electrons in an atom that can have these quantum numbers: a) n =0, 1 =0, m = 0 b) n =2, 1 = 1, m = -1, m = -1/2 c) n=3 d) n=2,1=2 e) n =1, 1 =0, m = 0

Answer 1

5p (n=5), no of orbitals = ☺ in 5b, which have different Jhere are three Þorb orientations. 5bx, 5py, ree Þ Orbitals 5px 5py, 5 pz o 3d7% (n=3), no. of orbitals = ☺ Jotal 5 orientahons = dyz dz2 dny, dxz, da?-y? 4d 2², 4 dxz 14day, 42x²-47 4d (n=4), no. of orbit As mentioned above: 4dy z, 402, 4drzi n=4 n² = 16 n = 5 = 5=25 no. of orbitals = n n = 1, 2, 3 .... 1=0 (sorbital) 1. e= 0, 1,2..(n-1) 1 1=1 (p orbital) me = -l to l 2= 2 ( d orbital) ms= +1/21-/ 1=3 ct orbital) n o, not possible co to maximum no. of elechons = 0 n=2, l = 1, m, =-1, mg=%. 1=1 c p-orbital) 2p [ IN . m, = -0, 1, 1 H to e) m -TOI marimum no. of electron = Scanned with CamScanner

I am no. of elechons = 2(n = 219) = (18) (d ) n = 2, 1-2. 0, 1 Coton-1) of l = for n=2, possible vowes of So, l = 2 is not possible os no. of electrons = 0 (e) n=1, 1=0, m = 0 doo (sorbital). [11] (two) - mi O 1 mar m no. of electrons = 2 Scanned with CamScanner
