2,1,0,-1,-2 are the possible values of ml for an electron in d orbital.
A 3s electron
It outermost electron in Krypton is 4s1 so the quantum number set is: n l ml ms 4 0 0 1/2 n= principal quantum number l- angular shapes of the lob ml- orientation of the lobe ms- magnetic spin of the lobe , which always alternates between the values 1/2 and -1/2 Note that the quantum number l is always zero for the s orbital because there are only one subshell.
-l to l, so given l=2 (d orbital) the values for ml will be -2, -1, 0, +1, +2
The specific orbital within a sublevel
It's the azimuthal quantum number. It specifies the angular momentum of the orbital, which can broadly speaking be thought of as its "shape." (The reason I'm putting that in quotation marks is that it's possible for two orbitals with the same azimuthal quantum number to appear rather different in overall shape.)
n : 2 l : 1 ml : -1, 0, or 1
For the d orbital, the value of l is 2 and the value of ml is - l to + l, so the values of ml would be -2, -1, 0, +1, +2. So, the maximum value would be +2.
A 3s electron
The magnetic quantum number ml depends on the orbital angular momentum (azimuthal) quantum number, l, which in turn depends on the principal quantum number, n. The orbital angular momentum (azimuthal) quantum number, l, runs from 0 to (n-1) where n is the principal quantum number. l= 0 is an s orbital, l= 1 is a p subshell, l= 2 is a d subshell, l=3 is an f subshell. The magnetic quantum number, ml, runs from -l to +l (sorry this font is rubbish the letter l looks like a 1) so for an f orbital the values are -3. -2, -1, 0, +1, +2, +3, so 7 f orbitals in total. ml "defines " the shape of the orbital and the number within the subshell.
Four: Principal (n) - shell Azimuthal (l) - subshell Magnetic (ml or just m) - orbital orientation Spin (ms or just s) - electron's angular momentum
The quantum number set of the ground-state electron in helium, but not in hydrogen, is (1s^2) or (n=1, l=0, ml=0, ms=0). It indicates that the electron occupies the 1s orbital, which has a principal quantum number (n) of 1, an orbital angular momentum quantum number (l) of 0, a magnetic quantum number (ml) of 0, and a spin quantum number (ms) of 0.
There is no difference. Electrons are subatomic particles and therefore identical.Added:In the same orbital, defined by one 'tri' set of quantum numbers (n, l, and ml ) the spin quantum number differs, the two values being ms = +1/2 and ms = -1/2, are each taken by one electron.
They act as codes that provide information about each electron in an atom. n - energy level (can be 1,2,3…) l - orbital shape (s=0, p=1, d=2) ml - orbital orientation (goes from -/to +/by integers) ms - spin (arrow up or down, and can be either +½ or -½)
It outermost electron in Krypton is 4s1 so the quantum number set is: n l ml ms 4 0 0 1/2 n= principal quantum number l- angular shapes of the lob ml- orientation of the lobe ms- magnetic spin of the lobe , which always alternates between the values 1/2 and -1/2 Note that the quantum number l is always zero for the s orbital because there are only one subshell.
-l to l, so given l=2 (d orbital) the values for ml will be -2, -1, 0, +1, +2
The magnetic quantum number, ml, runs from -l to +l (sorry this font is rubbish the letter l looks like a 1) where l is the azimuthal, angular momentum quantum number. The magnetic quantum number ml depends on the orbital angular momentum (azimuthal) quantum number, l, which in turn depends on the principal quantum number, n. The orbital angular momentum (azimuthal) quantum number, l, runs from 0 to (n-1) where n is the principal quantum number. l= 0 is an s orbital, l= 1 is a p subshell, l= 2 is a d subshell, l=3 is an f subshell. The magnetic quantum number, ml, runs from -l to +l (sorry this font is rubbish the letter l looks like a 1). ml "defines " the shape of the orbital and the number within the subshell. As an example for a d orbital (l=2), the values are -2, -1, 0, +1, +2, , so 5 d orbitals in total.
