    Is this 4?

    What is the rule for L?

    L = an integer from 0 to n-1

    So when n=4, L could have values of.. ?

    IF 4-1 is 3 then it could have values from 0 to 3. So 0,1,2,3. That is 4 possible values

    I don't understand this one: How many electrons in an atom can share the quantum numbers n= 2, l = 1, and m subscript l = -1? (2 points) 2 4 6 8

    (2,1,-1, ) Is it similar to the last question?

    Since 3 of the 4 are the same, the only QN that will be different is the last one. How many possible values can ms have?

    ms can have 2 values

    Since there are only 2 possible values and 3 of the 4 are already assigned, how many electrons will have those QNs?

    (2, 1, -1, +1/2) is the first, and (2, 1, -2, -1/2) must be the second. No other possibilities exist

    That second one should still be (2, 1, -1, -1/2)

    You should close all these finished questions to free up the space
