Question

For each value of l the number of m value is ?

Answer 1

Well, your set of quantum numbers is not "allowed" for a particular electron because of the value you have for

l

, the angular momentum quantum number.

The values the angular momentum quantum number is allowed to take go from zero to

n-1

,

n

being the principal quantum number.

So, in your case, if

n

is equal to 3, the values

l

must take are 0, 1, and 2. Since

l

is listed as having the value 3, this puts it outside the allowed range.

The value for

m

l

can exist, since

m

l

, the **magnetic quantum number, ranges from

−

l

, to

+l

.

Likewise,

m

s

, the spin quantum number, has an acceptable value, since it can only be

−

1/2

or

+

1/2

.

Therefore, the only value in your set that is not allowed for a quantum num

Answer 2

Heya...

• The four quantum numbers are the basis for a lot of chemical properties. Complete Step by step answer: The symbol l represents azimuthal quantum number. The symbol m represents a magnetic quantum number. For a given value of l , the total number of ' m ' values are 2l+1 .
