Use equation 26.8 (Zeeman Effect). This is a simple plug-in calculation.
e = charge of an electron (1.6E-19)
h = Planck's constant (6.6E-34)
B = magnetic field
m = mass of an electron (9.1E-31)
The answer we get is in Joules. Convert this to eV, and that is the final answer.

l = n-1
Plug in your given principal number to find l.
Then, as sheet 46' shows, lay out the possible orbital states for all numbers of l, from 0 --> n-1. Then, count the quantum states available in the highest value of l.
So, for example: n=3
l = n-1 = 3-1 = 2
l=0 --> 0
l=1 --> -1, 0, +1
l=2 --> -2, -1, 0, 1, 2
Since l=2 is the highest orbital momentum level, there are 5 states available. That is the answer.
Answer is negative.

Procedure is shown on sheet 55.
Find l, and then list out all possible states for that all. Then, assume each possible state has 2 electrons. That is your answer.
Answer is positive.

question 2
I have tried several times to plug in the numbers into the equation for number 2 do you think you could post a more detailed explanation of how you did it because I keep getting the wrong answer.

question 2
I dont understand number 2 either if someone could please explain I would really appreciate that.

Alright. The equation is:
E = ml * ((e*h*B)/(4*pi*m))
Now, plug in numbers:
ml = Number given.
e = charge of an electron (1.6E-19)
h = Planck's constant (6.6E-34)
B = magnetic field given
m = mass of an electron (9.1E-31)
Solve, and it gives you the energy in conventional units. Convert this into electron volts (eV). This is the answer.

having prob with # 1
hey guys, im' having a real problem figuring out how to get # 1
heres the question once again:
The quantum mechanical electron in the hydrogen atom has the orbital (angular momentum) quantum number l = 6. How many quantum states are available to the electron (sheet 45) ? (Disregard electron spin)

# 1
can someone please explain how to answer question number 1. what are the steps behind the answer?

#1
same exact way as #3 if I=4 then ur answer would be 9 because
-4,-3,-2,-1,0,1,2,3,4
answer is positive
-4,-3,-2,-1,0,1,2,3,4
answer is positive

Q#2, #4
Q#2.
I used the equation given above but I still can't get the right answer. my quantum number m = -3 which equal ml?
Q#4.
I can't get that either. Must not be my day:)

number 4
i'm pretty sure the answer is to take your n and subtract 1 to get your l. from here, you need to know the structure of an atom, or follow this chart:
0= s = 2 electrons
1= p= 6 "
2= d= 10 "
3= f= 14 "
4= g= 18 "
5= h= 22 "
6= i= 26 "
so my problem:n=4
n-1=1 therefore 4-1=3
follow 3 across on the chart and get 14, which was my answer.
positive.
hope it works for everyone.

Re: Maple TA 26_3
I still can't get #2
can u guys do ur problems and plug it in
cause i keep getting different answers and all wrong
i converted by dividing the answer by 1.6E-19
