Question

illustrate (n+1) rule by taking 4s and 3d orbitals as example​

Answer 1

n+1 rule

for 4s

4+0=4

For 3d

3+2=5

here you need to follow azimuthal quantum no

0= s orbital

1= p orbital

2 =d orbital

3 =f orbital

Answer 2

Answer:

According to (n+l) rule, electrons in 4s should be filled before 3d.

Step-by-step explanation:

According to (n+l) rule the orbital having least value for (n+l) will be filled first with the electrons.

values of l

for

s = 0

p = 1

d = 2

f = 3

For example,

In 4s Value of (n+l) = 4 + 0 = 4

In 3d value of (n+l) = 3 + 2 = 5

So according to the (n+l) rule electrons in the 4s orbital will be filled earlier than the 3d orbital.
