Which set of numbers gives the correct possible values of i for n = 2?
0
0,1
o ,1, 2
o ,1, 2, 3

0,1

Explanation:

There are four quantum numbers:

Principal quantum number (n)

Azimuthal quantum number (l)

Magnetic quantum number (ml)

Spin quantum number (ms)

All these four quantum numbers gives complete information about an electron like its spin, shells, subshells and orbitals.

For example:

If n=2 than possible sets of quantum numbers are:

Azimuthal quantum number (l)

The azimuthal quantum number describe the shape of orbitals. Its value for s, p, d, f... are 0, 1, 2, 3. l= n-1

(n-1)

2-1 = 1

For n=2 there are two subshell s and p.

s = 0

p= 1

Magnetic quantum number (ml)

It describe the orientation of orbitals. Its values are -l to +l. For l=1  the ml will be  -1 0 +1

Spin quantum number (ms)

The spin quantum  number tells the spin of electron either its clock wise (+1/2) or anti clock wise (-1/2).

If the electron is added in full empty orbital its spin will be +1/2 because it occupy full empty. If electron is already present and another electron is added then its spin will be -1/2.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
