*Quantum Number*
1)Principal quantum no(n)
this quantum number determines the main energy level or sell to which electron belongs and have values of n n=1,2,3,4
n value can never be zero
2n^2
n=1. 2e
n=2. 8e
n=3. 18e
n=4. 32e
2) Azimeuthal quantum number(l)
It is it is also called secondary angular or quantum no.number it gives the subshell to which electron belongs
Allowted values 0 to n-1
If n=1. The values l=0
n=2. The values l=0
1
n=3. The values l=0
1
2
n=4. The values.l=0
1
2
3
When l=o then it is the *s* subshell
When l=1 then it is the *p* subshell
When l=2 then it is the *d* subshell
When l=3 then it is the *f* subshell
In every sabse electronica field on the basis of formula =2(2l+1)
Subshell
l=o. 2e. S
l=1. 6e. P
l=2. 10e. D
l=3. 14e. f
3) magnetic quantum number(m)
It is explain zeeman effect
Describe the behaviour of an electron in magnetic
Values of m are (-l through o+l)
Suppose n=3. L. Subshell
O. [] s
1 -1,o,1. [][][] p
2 -2,-1,o,1,2. [][][][][] d
4) spin quantum number(s)
An electron can spin clockwise or anticlockwise that is into two opposite direction
+1/2 and -1/2 orientation are clockwise or anticlockwise
Shapes of the orbital
* s* orbit shaped
Properties
1) d orbital are double dumbbell in shape
2)They are denoted as( dxy dyz dxz dx^2y^2 dz^2)
