1.	The total number of orbitals associated with the principal quantum number n = 3 is ...(a) 9 (b) 8 (c) 5 (d) 7
Answer» (a) 9 n = 3; l = 0; m₁ = 0 – one s orbital n = 3; l = 1; m₁ = -1, 0, 1 – three p orbitals n = 3; l = 2; m₁ = -2, -1, 0, 1, 2 – five d orbitals, overall nine orbitals are possible.

The total number of orbitals associated with the principal quantum number n = 3 is ...(a) 9 (b) 8 (c) 5 (d) 7

Answer»

(a) 9

n = 3; l = 0; m₁ = 0 – one s orbital n = 3; l = 1; m₁ = -1, 0, 1 – three p orbitals n = 3; l = 2; m₁ = -2, -1, 0, 1, 2 – five d orbitals, overall nine orbitals are possible.
