Answer:
The valid quantum numbers are l=0, l=-2 and l= 2.
Explanation:
Given that,
n = 3 electron shell
Suppose, the valid quantum numbers are
l = 3
m = 3
l = 0
m = –2
l = –1
m = 2
We know that,
The value of n = 3
Principle quantum number :
Then the principal quantum number is 3. Which is shows the M shell.
So, n = 3
Azimuthal quantum number :
The azimuthal quantum number is l.

Magnetic quantum number :
The magnetic quantum number is

Hence, The valid quantum numbers are l=0, l=-2 and l= 2.

1023 molecules or atoms depending on substance
I would say physical, because a physical change is affecting the form of a chemical substance, but not it's chemical makeup.
