Question

Describe the orbital with following quantum numbers:
$\left(i\right)n=3,l=2\left(ii\right)n=4,l=3$

• A. $\left(i\right)3p,\left(ii\right)4f$
• B. $\left(i\right)3d,\left(ii\right)4d$
• C. $\left(i\right)3f,\left(ii\right)5f$
• D. $\left(i\right)3d,\left(ii\right)4f$

Answer 1

Answer: (D)

$\left(i\right)3d,\left(ii\right)4f$

Value of l

s: l = 0

p: l = 1

d: l = 2

f: l = 3

So for n=3,l=2

orbital is 3d

So for n=4,l=3

orbital is 4f
